Abstract

This paper discusses the problem of eliminating brightness nonuniformity on color endoscopic images with a large dynamic brightness range and of converting a sequence of such images into one image with a brightness range that can be reproduced on the screen of a standard monitor. A rapid and stable algorithm is proposed that is based on combined multiscale analysis of the images and histogram processing of the images at each level of a pyramidal representation. The efficiency of the algorithm is confirmed by examples and a comparison with known methods.
