Merging pixels´ location and illumination levels information for getting automatic fuzzy perceptual image segmentation algorithms

Monochrome digital images have a discrete set of illumination levels. So, results of monochrome images segmentation algorithms could be notably improved if human being´s ability, for distinguishing these levels, would be considered within this type of algorithms. Although illumination levels provide a lot of information about the objects appearing within an image, to be considered within segmentation algorithms, gray levels constituting each illumination level has to be specified. As a part of our ongoing work for getting fuzzy perceptual segmentation algorithms, here we present a system for recognizing the image´s illumination levels wherein, with the aim of simplifying the problems and automating the process, besides the analysis of image´s gray levels histogram, location of the pixels associated with each histogram peak is also considered.
