Embodiment 1

[0063] This embodiment provides a method for detecting and screening round cell regions, such as figure 1 shown, including steps:

[0064] S11: Define the gray level structure information with different importance in phase contrast microscope cell images;

[0065] S12: Determine the main cell information of the current frame by manual marking or inter-frame association;

[0066] S13: Perform Hough circle detection on the original image and obtain the position parameters and radius parameters of each Hough circle;

[0067] S14: Screen the Hough circle detection results by comparing the main information of each cell with the relationship between each Hough circle area.

[0068] In this embodiment, firstly, the hierarchical structure information with different importances of the phase contrast microscope cell image is defined, that is, primary cell information, intermediate cell information and secondary cell information. Then, the main cell information of the current frame is...

Abstract

The invention discloses a method and a system for detecting and screening quasi-circular cell regions to solve the problem that the quasi-circular cell regions cannot be effectively detected and screened in the prior art. The method comprises: S1: defining grayscale hierarchical structure information with different importance in the phase contrast microscope cell image; S2: determining cell main information of the current frame by means of manual marking or inter-frame correlation; S3: performing Hough circle detection for the original image and obtaining the position parameters and the radiusparameters of each Hough circle; and S4: screening the results of the Hough circle detection by comparing the relationship between the main information of each cell and each Hough circle region. Themethod and the system are based on the grayscale hierarchical structure information. By comparing the relationship between the main information of each cell and each Hough circle region, the results of the Hough circle detection can be effectively distinguished and screened, thereby facilitating the determination of cell morphology and its changes.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, and in particular to a method and system for detecting and screening round-like cell regions. Background technique [0002] The study of cell movement has always been an important part of cytology and biology research, but the traditional research method has gradually become less applicable as the technology is becoming more and more innovative. , Classification, counting, tracking, etc. not only require a lot of tedious human operations, but also tend to make the operator fatigued and affect the correctness of the results, and their reusability is relatively low. [0003] After long-term practice and research, medical experts at home and abroad have reached a consensus that digital video technology and digital image processing technology should be introduced in cell movement research, thereby greatly improving research efficiency and reducing the burden on researchers. ...
