Original Abstract
A method for correction of non-homogenous illumination based on optimization of parameters of B-spline shading model in respect to the Shannons entropy is presented. An analytical gradient term of the entropy criterion has been derived allowing to use the efficient L-BFGS optimization algorithm. The method has been tested on the set of 20 retinal images and has shown ability to substantially eliminate the illumination distortion. The application of this method for reliable image segmentation or registration was tested.
