title: [A nucleus area extraction method for image analysis of kidney-tissue slice].
abstract: To analyze the nuclei in the glomeruli of human kidneys, the problem of miss extraction or wrong extraction of nuclei caused by the effects of many factors during making slice must be solved. Aiming at this question, this paper proposed a dynamic thresholding method using eigenvalue feedback strategy based on multicenter. First, according to the information of R channel in the RGB color space and the information of C channel in the CMYK color space, after the process of filtering by LOG, we can get the correct positions of nuclei. Second, adjusting the threshold value surface by eigenvalue feedback strategy, we can solve the problem of conglutination of different nuclei. Then by combining the position information of nuclei, we can realize the nuclei segmentation accurately. The experimental results have demonstrated the high precision of this method.
