Siril | Siril is now fully capable to pre-process and process '''deep sky''' images. One feature still missing for '''planetary''' images processing is image deformation, but it is still capable of registering and processing them in an elegant way. The new star detection registration is perfect for deep sky images, but there are also two automatic translation-only registrations, one more suited for planetary and bright nebula images, based on [https://en.wikipedia.org/wiki/Discrete_Fourier_transform DFT], and another more simple targetted at deep-sky images, based on [http://en.wikipedia.org/wiki/Point_spread_function PSF] on a single reference star. Additionally, a manual alignment capability makes it also well fitted for amateur astronomers having feature-less or bad quality images that automatic tools fail to align properly. | ||
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. | Los astrónomos profesionales generalmente usan imágenes con profundidad de 32-bits, pero Siril usa únicamente imágenes de 16-bits (excepto temporalmente para el apilado).

Revision as of 22:24, 28 October 2015
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.
Current version is 0.9.0 stable version. Previous version were 0.9.0 beta and 0.9.0 rc1, now obsolete.
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.

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.

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.
Lista de Caracateristicas de Siril
New features are being introduced quite regularly. Here is a list of main features:
- Native image format support
- unsigned 16-bit FITS files (other FITS are converted to this format on-the-fly)
- SER files
- AVI and many other film files, their support is being dropped in favour of SER.
- 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:
- Global star alignment (rotation + translation)
- 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 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 available commands.
- A star finding algorithm with PSF information
Limitaciones
- En el espacio de trabajo general solo son posible imagenes de 3 canales de color asignados a R, G y B. Sin embargo es posible manipular muchas imagenes de un canal para crear una composicion de color, tales como las populares LRGB, RGBH o imagenes SII-Ha-OIII
Compilado e Instalacion
See Siril installation page. It documents which binary packages you can get and how to build from source if needed, for multiple operating systems. Siril is a free software, licence is GPL3. It will most likely never run or be supported on Windows family operating systems.
Quien esta detras de Siril?
El jefe de proyecto de esta nueva version es Vincent. El tiene un PhD en ciencias de la computacion, y usa Siril como aficionado para procesar imagenes de una Canon EOS y una camara B&N QSI en un telescopio de 410mm.
Cyril tiene un PhD en fisica, motiva nuevos desarrollos y provee algoritmos de proceso de alta calidad a Siril.
François Meyer escribio las versiones iniciales (hasta la v0.8). Aqui esta el Sourceforge proyecto original y sitio web.
