Siril, un software de procesamiento de im&aacute;genes gratuito
<span style="color: #ff0090; font-weight: bold; text-align: center; margin: 2em; font-size: 125%;">This page is now deprecated. Please refer to the new [https://siril.org Siril website] or [https://siril.readthedocs.io/en/stable/ documentation].</span>


Siril is meant to be Iris for Linux (sirI-L). It is an astronomical image processing tool, able to convert, pre-process images, help aligning them automatically or manually, stack them and enhance final images. This page is the page for the new version of Siril.

<div class="mw-translate-fuzzy">
Siril significa Iris for Linux (sirI-L). Es una herramienta para procesar im&aacute;genes astron&oacute;micas, capaz de convertir y  pre-procesar im&aacute;genes, ayudar a alinearlas de modo autom&aacute;tico o manual, apilarlas y mejorar las im&aacute;genes finales. Esta p&aacute;gina es la p&aacute;gina para la nueva version de Siril.
</div>


==Who should use Siril?==
{{:Siril:Links}}
Siril is targeted to '''amateur astronomers''' having acquired images and wanting to process them in a semi-automatic way. It provides a more user-friendly interface than Iris' command line, but it is not yet as automated as DeepSkyStacker or Registax. It also provides a command line to access various processing functions.


Siril is able to process '''planetary''' images (many small images) as well as '''deep sky''' images (a few large images with full pre-processing data). Registration is able to automatically align (translation only) planetary images, using [https://en.wikipedia.org/wiki/Discrete_Fourier_transform DFT], as well as deep-sky images, using [http://en.wikipedia.org/wiki/Point_spread_function PSF] on a reference star, as long as the shift between images in not too large. The manual alignment capability makes it also well fitted for amateur astronomers having bad quality images that automatic tools fail to align properly.
<randomimage size="600" float="center" choices="Lovejoy_300mm_Cyp.jpg|Cassiopeia_Cyp.jpg|Lovejoy_VB.jpg|Lovejoy_Cyp.jpg|Lune-TFG-2014-04-07.jpg|Star-trails.jpg|M33.jpg|NGC7635.jpg|Siril_M8-M20_processed.png|Jupiter.png|Cygnus_loop_fphg.jpg|M27_Cyp.jpg|M33_Cyp.jpg">This image was processed using Siril, see other [[Siril:Results|processing results]].</randomimage>


Professional astronomers generally use 32-bit depth images, but Siril uses only 16-bit images internally (except temporary for stacking). Loading 32-bit images is supported but it will degrade them since they will be converted to 16-bit. It can still be useful if the intent is to produce public-friendly pictures.
<div class="mw-translate-fuzzy">
==Qui&eacute;n deber&iacute;a usar Siril?==
Siril est&aacute; dirigido a '''astr&oacute;nomos aficionados''' que han tomado im&aacute;genes y quieren procesarlas de manera semi-autom&aacute;tica. Entrega una interfaz mas amistosa que la l&iacute;nea de comandos de Iris, pero no es aun tan automatizado como DeepSkyStacker o Registax. Tambi&eacute;n provee una l&iacute;nea de comandos para accesar varias funciones de procesamiento.
</div>


And more generally, people who want to use free software on free operating systems to process images. Siril can even be used to extract previewed frames from many videos formats. For an overview, see some image processing [[Siril:Results|results]], or [[Siril:Manual|documentation]] pages.
<div class="mw-translate-fuzzy">
Siril puede procesar tanto im&aacute;genes '''planetarias''' (muchas im&aacute;genes peque&ntilde;as) como im&aacute;genes de '''cielo profundo''' (unas pocas im&aacute;genes grandes con todos los datos de pre-procesamiento).
El registro es capaz de alinear autom&aacute;ticamente (s&oacute;lo traslaci&oacute;n) im&aacute;genes planetarias, usando [https://en.wikipedia.org/wiki/Discrete_Fourier_transform DFT], as&iacute; como tambi&eacute;n im&aacute;genes de cielo profundo, usando [http://en.wikipedia.org/wiki/Point_spread_function PSF] en una estrella de referencia, siempre y cuando el desplazamiento entre im&aacute;genes no sea muy grande. La capacidad de alinear manualmente lo hace tambi&eacute;n apropiado para astr&oacute;nomos aficionados con im&aacute;genes de mala calidad que las herramientas autom&aacute;ticas no pueden alinear de manera apropiada.
</div>


==News==
<div class="mw-translate-fuzzy">
*April 13, 2015
Los astr&oacute;nomos profesionales generalmente usan im&aacute;genes con profundidad de 32-bits, pero Siril usa &uacute;nicamente im&aacute;genes de 16-bits (excepto temporalmente para el apilado). Se pueden cargar im&aacute;genes de 32-bits pero ser&aacute;n degradadas al ser convertidas a 16-bits. A&uacute;n as&iacute; puede ser &uacute;til si la intenci&oacute;n es producir im&aacute;genes para el p&uacute;blico general.
**We have been working hard on accelerating stacking algorithms on multi-core CPUs, giving SER a better support and we are also working on the two main lacks of Siril: taking into account rotation and multi-point in registration, for better deep-sky and planetary registrations. These works are in progress, and will take some weeks to complete.

<div class="mw-translate-fuzzy">
Y de manera m&aacute;s general, por aquellas personas que quieren usar software gratuito en sistemas operativos gratuitos para procesar im&aacute;genes. Siril puede incluso ser utilizado para extraer cuadros individuales desde varios formatos de video.

The software is in '''beta''' phase, meaning its stability is still being improved, but most functionalities are working. If you find bugs and want to report them (please, do!), contact the team using the links at the bottom of this page, or use the system provided by your OS.
*December 4, 2017
** A new 0.9.8 version is [https://gitlab.com/free-astro/siril/milestones/11 progressing well] and will particularly help people working on deep-sky lucky imaging.
** We have also started working on features for the next major version of Siril, '''version 1.0'''. The first development, started at the beginning of the year, aims to greatly speed up the display of images and the rendering effects and this looks very promising. Other major developments will be the use of a better precision, floating point, internal image format that will give better results with some algorithms, the parallelization of preprocessing and the creation of a high quality registration and stacking method for planetary images. It will still take a lot of time, but that will be a fully featured and fast version of Siril. Current 0.9.x versions are stable and already provide great results for deep-sky image processing.


Many [[Siril:0.9.0 beta|improvements]] have been done over the previous unmaintained version. The command line has been reactivated in large proportions, see the list of currently available commands on the dedicated [[Siril:Commands|Commands]] page. New commands and features have been and are being developed. For a complete list of features, see the [[Siril:0.9.0_beta|0.9.0 beta]] page, the subversion log, or the [[Siril#List_of_Siril_features|list of features]] below.

**New release [[Siril:0.9.7|0.9.7]]. Click [[Siril:releases|here]] for past releases. Siril is now available on '''Windows''' as a beta version!


The '''roadmap''' for Siril is being updated for its after-release life. The main coming developments are completely remaking the conversion and sequence features to handle any list of files, and providing a registration that takes image rotation into account. Ideas are stored in the [https://free-astro.vinvin.tf/svn/siril/src/TODO TODO] file, and the list of known bugs is maintained in the [https://free-astro.vinvin.tf/svn/siril/src/BUGS BUGS] file.

==Start using Siril / Documentation==
*November 28, 2016
Siril's works internally with FITS images, unsigned 16-bit per pixel and per channel. All images you want to process with Siril thus needs to be converted using the [[Siril:Tutorial_import|Conversion tab]], except for SER and film sequences which are converted on-the-fly.
**New release [[Siril:0.9.5|0.9.5]]. Click [[Siril:releases|here]] for past releases. Development of major improvements such as native 32 bit images and [https://www.libvips.org/ vips] rendering has started.


For pre-processing, Siril applies ''master'' offset/bias, dark and flat images to the current sequence. These master images thus have to be processed before processing the actual image sequence. Siril currently does not support processing multiple sequences at the same time, so each layer of the final image must be processed independently before assembling them into an RGB image.
*October 8, 2016
**A new team member has given a huge effort to bring you a fantastic new multi-language documentation, both [https://free-astro.org/siril_doc-en/ browsable] and in [https://free-astro.org/download/siril-doc-0.9.9-en.pdf PDF].


A '''[[Siril:Manual|documentation page]]''' contains an illustrated [[Siril:Manual#Tutorial_for_a_complete_sequence_processing|complete processing tutorial]], instructions on how to use particular features of Siril, along with a few videos to illustrate or describe these capabilities.

*October 28, 2015
**First stable version available: [[Siril:0.9.0|0.9.0]]. Stability updates and minor improvements will occur in the dedicated 0.9 branch.


==List of Siril features==
*June 10, 2015
**New registration method available! It is now possible to register images with an automatic global star detection tool. The algorithm takes into account the translation and the rotation.


New features are being introduced quite regularly. Here is a list of main features:
*April 13, 2015
* Native image format support
**We have been working hard on accelerating stacking algorithms on multi-core CPUs, giving SER a better support and we are also working on the two main lacks of Siril: taking into account rotation and multi-point in registration, for better deep-sky and planetary registrations. These works are in progress, and will take some weeks to complete.
** unsigned 16-bit FITS files (other FITS are converted to this format on-the-fly)
** SER files
** AVI and many other film files
* Image conversion (to the native FITS format only)
** Supported input types: 8-bit and 16-bit BMP, TIFF, JPEG, PNG files, NetPBM binary images, RAW DSLR images.
* Image registration; supported methods:
** Translation using DFT centered on an object, generally used for planetary images
** Translation using PSF of a star, generally used for deek-sky images
** Manual translation with two preview renderings of the current image with reference frame in transparency
** Image rotation and plate-solving are not implemented yet
* Image stacking
** Summing
** Median
** Percentile clipping
** Sigma clipping
** Median sigma clipping
** Winsorized sigma clipping
** Linear fit clipping
** Pixel maximum
* Pre-processing of images with multi-channel offset, dark and flat images
* Enhancement of final images: lightness/contrast cursors on each layer, different scaling modes (linear, log, square root, squared, asinh, histogram equalisation), negative and false colour rendering and clipping.
* A command line for various processing functions, see the list of [[Siril:Commands|available commands]].
* A star finding algorithm with PSF information


'''Limitations:'''
<div class="mw-translate-fuzzy">
* Only 3-channel colour images assigned to R, G and B are possible in the general workspace (image processing and sequence handling). It is however possible to manipulate many 1-channel image to create a colour composition, such as popular LRGB, RGBHa or [http://hubblesite.org/gallery/behind_the_pictures/meaning_of_color/eagle.php SII-Ha-OIII] images.
Varias [[Siril:0.9.0 beta|mejoras]] se han hecho sobre la version anterior. La linea de comandos ha sido reactivada en su mayoria, vea la lista de comandos actualmente disponibles en la pagina dedicada [[Siril:Commands|Comandos]]. Nuevos comandos y caracteristicas se han y se estan desarrollando. Para una lista completa de caracteristicas, vea la pagina [[Siril:0.9.0_beta|0.9.0 beta]], el log de subversion, o la [[Siril#List_of_Siril_features|lista de caracteristicas]] mas abajo.

==Compilation and installation==
<div class="mw-translate-fuzzy">
La '''hoja de ruta''' de Siril esta siendo actualizada para su vida despues de la liberacion. Los principales desarrollos venideros son rehacer completamente la secuencia y la conversion para manejar cualquier lista de archivos, y proveer un metodo de registro que tome en cuenta la rotacion de la imagen. Las ideas se guardan en el archivo [https://free-astro.vinvin.tf/svn/siril/src/TODO TODO], y la lista de fallas conocidas se mantiene en el archivo [https://free-astro.vinvin.tf/svn/siril/src/BUGS BUGS]. El registro de cambios completo se encuentra en SVN (no disponible online), un resumen se encuentra en la seccion noticias, asi como en el archivo [https://free-astro.vinvin.tf/svn/siril/ChangeLog ChangeLog] '''Si Ud. quiere contribuir, sea bienvenido'''
</div>


Since 0.9.0b, Siril is released as source package or binary package in various distributions. The other choice is accessing the development trunk in the subversion repository. There is a package for the Arch Linux system, built from the subversion source, [https://aur.archlinux.org/packages/siril/ in AUR]. Siril has also been tested and reported running on MacOS but needs a specific installation, please see the [[Siril:install#Installing_on_MacOS|dedicated page]].

===Dependencies===
<div class="mw-translate-fuzzy">
Siril depends on a number of libraries, which all should be available in your operating system if it is recent enough. See a list of packages names for Debian [[Siril:install|here]]. Mandatory dependencies are:
Para el pre-procesamiento, Siril usa imagenes ''master'' de offset/bias, darks y flats. Estas imagenes master deben ser procesadas antes de procesar la secuencia de imagenes. Siril actualmente no soporta procesar multiples secuencias al mismo tiempo, por lo que cada capa de la imagen final debe ser procesada de manera independiente antes de ensamblarla en una imagen RGB.

Siril, un software de procesamiento de imágenes gratuito

Siril significa Iris for Linux (sirI-L). Es una herramienta para procesar imágenes astronómicas, capaz de convertir y pre-procesar imágenes, ayudar a alinearlas de modo automático o manual, apilarlas y mejorar las imágenes finales. Esta página es la página para la nueva version de Siril.

  • New website: siril.org. Please use it instead of this one for news, the new documentation and tutorials.
  • Current version is 1.2.0. See the list of previous versions here.
  • Siril forum
  • Code source, bug reporting and roadmap is now on gitlab


This image was processed using Siril, see other processing results.


Quién debería usar Siril?

Siril está dirigido a astrónomos aficionados que han tomado imágenes y quieren procesarlas de manera semi-automática. Entrega una interfaz mas amistosa que la línea de comandos de Iris, pero no es aun tan automatizado como DeepSkyStacker o Registax. También provee una línea de comandos para accesar varias funciones de procesamiento.

Siril puede procesar tanto imágenes planetarias (muchas imágenes pequeñas) como imágenes de cielo profundo (unas pocas imágenes grandes con todos los datos de pre-procesamiento). El registro es capaz de alinear automáticamente (sólo traslación) imágenes planetarias, usando DFT, así como también imágenes de cielo profundo, usando PSF en una estrella de referencia, siempre y cuando el desplazamiento entre imágenes no sea muy grande. La capacidad de alinear manualmente lo hace también apropiado para astrónomos aficionados con imágenes de mala calidad que las herramientas automáticas no pueden alinear de manera apropiada.

Los astrónomos profesionales generalmente usan imágenes con profundidad de 32-bits, pero Siril usa únicamente imágenes de 16-bits (excepto temporalmente para el apilado). Se pueden cargar imágenes de 32-bits pero serán degradadas al ser convertidas a 16-bits. Aún así puede ser útil si la intención es producir imágenes para el público general.

Y de manera más general, por aquellas personas que quieren usar software gratuito en sistemas operativos gratuitos para procesar imágenes. Siril puede incluso ser utilizado para extraer cuadros individuales desde varios formatos de video. Para formase una idea, vea algunos resultados, o las páginas de documentación.

    • Hemos estado trabajando duro para acelerar los algoritmos de apilado en las CPUs multi-core, dándole mejor soporte a SER y estamos también trabajando en las dos principales faltas de Siril: tomar en cuenta la rotación y el multi-punto durante el registro, para obtener mejores imágenes de cielo profundo y planetarias. Estos trabajos están en progreso, y tomará algunas semanas para compleatrlo.

We are looking for volunteer translators, for the software and for the documentation. No programming experience is required. See the translation instructions page for software translation. In any case, check the status of your language translation with Cyril (at free-astro.org) if you want to help.

El software está en fase beta, lo que significa que su estabilidad está siendo mejorada, pero la mayoría de las funciones están trabajando. Si encuentra una falla y quiere reportarla (por favor, hágalo), contcate al equipo usando los enlaces al final de esta página, o utilice el sistema proporcionado por su S.O.

Please use this modern way of communicating with us about code and problems now. The address of the project is https://gitlab.com/free-astro/siril/ . It's been a long year for us with many unfinished business for the 1.0 version. In the meantime, we are preparing a 0.9.10 stability release for very soon.
  • June 7, 2018
    • The new 0.9.9 version has been released, with bug fixes, and new script feature.
  • February 19, 2018
    • A patch of the 0.9.8 version has been released: 0.9.8.3.
  • January 31, 2018
    • The new 0.9.8 version has been released, with bug fixes, improvements on lucky imaging and Windows integration.
  • December 4, 2017
    • A new 0.9.8 version is progressing well and will particularly help people working on deep-sky lucky imaging.
    • We have also started working on features for the next major version of Siril, version 1.0. The first development, started at the beginning of the year, aims to greatly speed up the display of images and the rendering effects and this looks very promising. Other major developments will be the use of a better precision, floating point, internal image format that will give better results with some algorithms, the parallelization of preprocessing and the creation of a high quality registration and stacking method for planetary images. It will still take a lot of time, but that will be a fully featured and fast version of Siril. Current 0.9.x versions are stable and already provide great results for deep-sky image processing.

Varias mejoras se han hecho sobre la version anterior. La linea de comandos ha sido reactivada en su mayoria, vea la lista de comandos actualmente disponibles en la pagina dedicada Comandos. Nuevos comandos y caracteristicas se han y se estan desarrollando. Para una lista completa de caracteristicas, vea la pagina 0.9.0 beta, el log de subversion, o la lista de caracteristicas mas abajo.

La hoja de ruta de Siril esta siendo actualizada para su vida despues de la liberacion. Los principales desarrollos venideros son rehacer completamente la secuencia y la conversion para manejar cualquier lista de archivos, y proveer un metodo de registro que tome en cuenta la rotacion de la imagen. Las ideas se guardan en el archivo TODO, y la lista de fallas conocidas se mantiene en el archivo BUGS. El registro de cambios completo se encuentra en SVN (no disponible online), un resumen se encuentra en la seccion noticias, asi como en el archivo ChangeLog Si Ud. quiere contribuir, sea bienvenido

Comience a usar Siril/Documentacion

Siril trabaja internamente con imagenes FITS, sin signo de 16 bits por pixel y por canal. Todas las imagenes que quiera procesar con Siril deben ser convertidas usando la Pestaña de conversion, excepto las secuencias de SER y videos que son convertidas sobre la marcha.

Para el pre-procesamiento, Siril usa imagenes master de offset/bias, darks y flats. Estas imagenes master deben ser procesadas antes de procesar la secuencia de imagenes. Siril actualmente no soporta procesar multiples secuencias al mismo tiempo, por lo que cada capa de la imagen final debe ser procesada de manera independiente antes de ensamblarla en una imagen RGB.

Una pagina de documentacion contiene un tutorial completo de procesamiento, instrucciones para caracteristicas particulares de Siril, y unos pocos videos para ilustrar o describir estas capacidades.

For 1.0, we focused on describing the usage with tutorials, on the new website siril.org/tutorials. There are also frequently asked questions of great help.
