Application of improved multi-scale watershed algorithm in medical image segmentation
改进多尺度分水岭算法在医学图像分割中的应用研究

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.
