%X With regard to the over-segmentation of watershed algorithm and the characteristics of medical image, a new algorithm that can effectively enhance the edge of depth image and eliminate local minima was presented. Firstly, morphological gradient image was got by muti-scale filter, which can extract image edge effectively. Then, a new filter method based on image edge was proposed, which can eliminate local minima. Finally, procedures and results of the algorithm were introduced. Experimental results demonstrate that watershed transformation with the proposed algorithm produces very good segmentations, even without region merging.
