Abstract

The invention provides a cell segmentation method and device based on a multi-layer structure and electronic equipment. The method comprises the following steps: acquiring a to-be-segmented cell image; preprocessing the cell image to obtain a preprocessed image; performing coarse segmentation on the preprocessed image by adopting a watershed algorithm and an improved GVF Snake model to obtain a cell coarse contour; and performing fine cell segmentation on the coarse cell contour by combining convex hull detection, angular point detection and ellipse fitting to obtain a cell contour. According to the scheme, cell segmentation of a multi-layer structure is completed through pretreatment, coarse segmentation and fine segmentation, the cell segmentation precision is high, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of cell segmentation, and in particular relates to a cell segmentation method, device and electronic equipment based on a multi-layer structure. Background technique [0002] The development of micro-imaging and big data has led people to pay attention to computer-aided diagnosis of diseases, such as breast cancer, cervical cancer, colon cancer, prostate cancer, etc. In addition, the cell nucleus contains a large amount of pathological information, which plays an important role in automatic diagnosis, and its segmentation results directly affect the physiological state of cells. Biologists collect and label datasets containing various nuclei, and manual diagnosis relies heavily on clinician experience and is time-consuming. [0003] Existing cell segmentation methods generally adopt traditional segmentation methods and deep learning segmentation methods. The over-segmentation of traditional segmentation me...
