Abstract

The invention discloses a cell nucleus segmentation method based on attention learning, and relates to the cell nucleus segmentation problem in intelligent pathological diagnosis. The intelligent pathological diagnosis technology utilizes a deep learning technology to segment and identify abnormal cells in a cell image. However, there are few models for cell nucleus segmentation in cell images. The following problems exist: (1) the problems of cell nucleus overlapping and unobvious boundary are not considered, so that the segmentation precision is low; and (2) the contextual information of thecell nucleus edge is not considered, so that under-segmentation or over-segmentation is caused, and the subsequent classification result is influenced. Therefore, the invention provides a cell nucleus segmentation method based on attention learning. Experiments show that the model can effectively solve the problem of segmentation of overlapped cells, and the problems of under-segmentation or over-segmentation of unclear boundaries and the like. The invention is applied to cell nucleus segmentation in intelligent pathological diagnosis.

Description

technical field [0001] The invention relates to intelligent pathological diagnosis, especially cell nucleus segmentation Background technique [0002] Cervical cancer is the second leading killer of women's health. Globally, a woman dies from cervical cancer every two minutes. Early cervical cancer can be completely cured, so early diagnosis and early treatment are effective means to deal with cancer outbreaks. Liquid-based thin-layer cytology detection is currently the most commonly used cervical cancer detection technology in the world, and it can detect some precancerous lesions and microbial infections. However, the traditional pathological diagnosis completely relies on manual reading by doctors and naked eye observation. However, the workload is heavy and the diagnostic accuracy is low, so it is impossible to promote large-scale screening. With the development of computer image processing and artificial intelligence technology, pathological automatic diagnosis tech...
