Enhanced Correlation Coefficient Maximization

This is an algorithm dedicated to the planet surfaces taken from opencv 3.0

ECC Image Alignment Algorithm⚓

In short, ECC image alignment algorithm estimates the geometric transformation (warp) between the input and the template image and it returns the warped input image which must be close to the template one, as it is shown below. The estimated trasnformation is the one that maximizes the correlation coefficient between the template and the warped input image. (1)
