Color image understanding through a perceptual approach
Abstract
Until now, color image analysis has received little attention as regards to perceptual approach. However, it seems intuitively natural to pay more attention to the field of color perception, in order to have a better knowledge of the mechanism which effects color image vision.
The aim of this paper is to review the main aspects of color image analysis which are closely linked to color vision. Due to the complexity of human color perception, we only attempt to mention a few of its principles such as those linked to: - the interaction due to both spatial and chromatic vision. - the measure of the color difference between two elements spatially adjacent or distant. - the prediction of some adaptive chromaticity difference perception thresholds as regards to local or global observations. - the discrimination between adjacent regions marked by a small color variation or when they present distinct color textures. ...
