Image segmentation is one of the most demanding tasks in optical image processing. In this paper, a new algorithm based on a two variable reaction-diffusion equations is proposed. A stable auto-organized pattern can be obtained by choosing suitable control parameters. Several image processes including image binarization, contrast enhancement, edge detection and noise reduction can be achieved Compared with the conventional methods, the new algorithm indicates a higher accuracy and continuity for the image. Moreover, it can preserve the information such as edges during image processing of noise reduction.
