Sperm tail recognition method

Abstract

A sperm tail recognition method comprises the following steps: step 1, acquiring an image; step 2, acquiring a difference image; step 3, acquiring a tail image; 4, acquiring a sperm head region image;5, combining the tail image and the sperm head region image; and 6, filtering the bright spot area without the long-tail area within a preset distance to obtain a sperm area image. Through acquisition of the difference image, a bright spot area in the semen sample image is filtered out, so that a non-long-tail area is convenient to filter, and an image of impurities or cells, which are greatly different from the sperm structure, in semen is realized. Filtering of bright spot images without long-tail-shaped areas nearby can be achieved through a distance selection method, and then filtering ofbright spot areas of non-sperm cells is achieved. According to the method, impurities in the seminal fluid are accurately filtered, and researchers can count and research the seminal fluid conveniently.

Description

technical field [0001] The invention relates to the field of sperm detection, in particular to a sperm tail recognition method. Background technique [0002] In the late 1980s, computer-aided analysis (CASA) based on sperm quality developed rapidly. It has been found that the use of computer image analysis technology to automatically measure and evaluate various data of sperm has many advantages. It is not only easy to operate, fast in analysis speed, high in calculation accuracy, and good in repeatability. The inspection level reduces their workload, and can overcome the shortcomings of traditional measurement methods, such as time-consuming, poor measurement accuracy, and strong human subjectivity. [0003] Most of the analysis methods for semen in the prior art are as follows: firstly, by staining the semen sample, and then enlarging and collecting dynamic images under the microscope through a microscope and camera system, and counting or identifying sperm in the image. ...

AI Technical Summary

Problems solved by technology

[0004] 1. The staining of semen samples will affect the activity of sperm to a certain extent, thus affecting the analysis of semen quality;

[0005] 2. Since semen contains a lot of non-sperm components (round cells, impurities, etc.), it will affect the judgment of sperm count

[0007] Although this method can avoid the impact of the dyeing process on the activity of semen, many impurities will also appear as bright spots under the microscope, which has a similar display effect to sperm, thus affecting the calculation of the number of sperm by the CASA system
