Abstract

The vision is the only way that people receives image information. Retinex is the theory and method of image enhancement that is based on experiments and analysis of vision. Retinex enhances the image by processing reflection R and incident light L from the image S to obtain better vision quality. It is described that the image appears to reflect or transmit more or less of the light, varying from black to white for image and from black to colorless for transparent volume in this paper. The calculation shows the improvement of global and local image enhancement by Retinex algorithm for X-Ray medical images. Finally the analysis and comparison by experiments are discussed.
