【摘要】 为克服重叠骨髓细胞对图像分析造成的困难,需将重叠细胞群分离成单个细胞。为此,提出了一种基于流域分割的骨髓细胞二值显微图像的分割方法。首先,用迭代腐蚀方法从重叠细胞中检测出种子数。然后,以极限腐蚀集合作为种子点进行区域生长,直到原图的所有像素均被重新吸收。为了提高运算速度,在种子点选取和区域生长方面进行了控制处理。本研究在Matlab环境下运用此算法对多幅细胞图像进行了分割,实验结果表明,该算法能够得到较好的分割结果。更多还原

【Abstract】 To overcome the difficulty caused by the clustering cells in the analysis of image for marrowcell,a new watershed segmentation algorithm of binary images is proposed.A distance map is developed to determine the number of seeds due to iterative erosion.The ultra erosion aggregate is considered as seeds to separate the cell cluster,and images are grown by dilation from these seeds until all the image pixels are assimilated.In order to speed up the computation,the choice and growing of seeds are under control.The algorithm was realized by the Matlab software.The experimental result shows that a better segmented image can be obtained.更多还原
