Abstract:
A system, article, and method to perform light source estimation for image processing includes measuring a compactness of the distribution of the image data to select a light source.

Claim (Index 13):
A computer-implemented system of light source estimation comprising:\n a display; at least one processor communicatively coupled to the display; at least one memory communicatively coupled to at least one processor and storing image data of at least one image of a video sequence or at least one still photograph forming an image; and at least one light estimation unit communicatively coupled to the processor, and to operate by:\n obtaining image data of at least one image captured by a camera; \n forming a plurality of separate data distributions comprising separately applying, to the image data, lens shading correction tables each of a different illuminant of a set of available illuminants; \n mapping the data distributions in a chromaticity space; \n measuring the compactness of the individual data distributions on the chromaticity space; \n generating likelihoods that the individual data distributions are associated with the true illuminant of the image comprising using compactness measurements of the individual data distributions; and \n providing the likelihoods to correct color on at least one image.
