Abstract

The embodiment of the invention provides a chromosome segmentation method and device, and the method comprises the steps: inputting a target chromosome image into a pre-trained semantic segmentation model, obtaining an overlapping region set and a non-overlapping region set, and enabling the non-overlapping region set to comprise at least one initial non-overlapping region; under the condition that the overlapping region set comprises at least one initial overlapping region, determining all initial non-overlapping regions adjacent to each initial overlapping region and the number of first regions of all the adjacent initial non-overlapping regions; and determining a region splicing rule according to the number of the first regions, and splicing each initial overlapping region with all adjacent initial non-overlapping regions according to the region splicing rule to obtain a chromosome segmentation image. According to the embodiment of the invention, the chromosome segmentation accuracyand segmentation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a chromosome segmentation method and device. Background technique [0002] As we all know, in the field of chromosome detection, there is usually a need to process the chromosome metaphase map; for example, there are often overlapping chromosomes in the chromosome metaphase map, and these overlapping chromosomes need to be segmented for subsequent analysis of the number of chromosomes or nuclei. type for accurate detection. [0003] In the prior art, overlapping chromosomes are usually segmented based on image morphological processing. However, due to the complexity of chromosome overlap, the segmentation accuracy based on image morphological processing is low. Contents of the invention [0004] Embodiments of the present invention provide a chromosome segmentation method and device to solve the problem of low segmentation accuracy caused by segmenting overlapping chr...
