The invention discloses a quasi-circular overlapping target segmentation method, system and device and a storage medium, and the method comprises the steps: determining a to-be-segmented region in a to-be-segmented image according to the gray value of the to-be-segmented image; the to-be-segmented region refers to a region where two quasi-circular targets with overlapped regions are located; detecting an outer boundary of the to-be-segmented region according to a polygon approximation algorithm, and determining boundary feature points; performing ellipse fitting according to the boundary feature points, and determining candidate split point pairs; determining a target split point pair according to the candidate split point pair and a preset screening condition; determining an overlapping region in the region to be segmented according to the target split point pair; performing image segmentation on the overlapping region, and determining the boundary of the overlapping region; and superposing the overlapped region boundary and the outer boundary to complete segmentation of the to-be-segmented region. According to the method, the overlapping region is segmented, and the segmentation precision can be improved. The method provided by the invention can be used for segmenting a quasi-circular cell image.
Description
technical field [0001] The present application relates to the field of image processing, and in particular to a method, system, device and storage medium for segmenting similar circular overlapping objects. Background technique [0002] In the medical field, it is often necessary to take images of cells in order to study pathology in depth. Because the cells are not evenly distributed in the liquid, when taking cell images, it is often found that many cells overlap in the image. To quantify cell morphology or count cells, overlapping cells need to be segmented. Because the cells are approximately circular, algorithms such as watershed segmentation are generally used in the prior art, but these algorithms often lead to over-segmentation, thereby losing a lot of effective cell information. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present application pro...
