An algorithm for enhancing different regions of interest in bone radiographs using mathematical morphology is presented. The calculation of the local histogram equalization (LHE) of a gray scale image throws into relief different textures in the image. These textures are segmented using morphological operations which include morphological gradient and opening by reconstruction. All the operations can be implemented optically so the computational time decreases very fast with respect to digital processing. Digital results are shown and optical implementation is discussed.
