Inpainting for Over-Exposed Photographs

Abstract

The thesis presents an over-exposure correction method for photographs. The method corrects the lightness and color parts of the over-exposure regions of the photograph separately. For the lightness part, the well-exposed regions are compressed non-linearly and then the over-exposure regions are corrected based on a con dence function. For the color part, the color values of the small holes are corrected using spatial and chromatic bilateral filter, and the color values of the large regions are filled in by a patch-based inpainting algorithm.
