Abstract

The invention provides a cell segmentation method and device and a computer readable storage medium. The method comprises the steps of obtaining an original image; processing the original image to obtain an image Igram; processing the image Igray by adopting a local threshold method to obtain an image ICLT; processing the image Igray by adopting a LoG algorithm to obtain an image ILoG; performingfusion operation on the image ICLT and the image ILoG to obtain an image Ifuse; and carrying out cell segmentation on the image Ifuse to obtain a cell nucleus segmentation image. According to the invention, the color image is converted into the grayscale image Igray and then is segmented, so that the problems of false cell nucleus detection and missing detection caused by non-uniform color distribution in the original image can be avoided. According to the method, the cell nucleus pixel points are obtained by using a mode of fusing a constrained local threshold method and a LoG algorithm, so that the problems of false cell nucleus detection and missing detection caused by non-uniform intensity distribution in an original image can be avoided.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a cell segmentation method, device and computer-readable storage medium. Background technique [0002] Analysis of pathological images is an important clinical and research tool for tumor diagnosis and assessment. However, conventional manual-based qualitative or semi-quantitative analysis often has subjectivity, individual differences, and irreproducibility. The cell nucleus is the basic unit of pathological images, and it is usually the place where biomarkers are concentrated. The automatic segmentation and counting technology of cell nuclei based on image processing can obtain objective quantitative data quickly, accurately and reproducibly, thereby improving the analysis efficiency of pathological images. The difficulty of cell nucleus segmentation and counting lies in the diversity of cell nucleus morphology, uneven intensity or staining distribution of nu...
