 # In depth  :
 This module allows for fast, subpixel accurate, robust registration. It essentially performs stochatic gradient decent using a first order taylor polynomial aproximation of the gradient. This is very similar to whats found in cv2 / matlab imregister. The ECC ( enhanced correlation coefficient ) algorithm is also implemented which adds robustness and reduces the numbers of needed itterations. This registration can use pyramiding ( or not - npyramids = 1 ) to deal with relatively large transformations. The registration is homography only ( no affine, translation, similarity ...etc options ( yet )).
