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

Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings, wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower", "bottom" and "top" used in the following description refer to the Directions, the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

[0053] A sperm tail identification method, such as figure 1 shown, including the following steps:

[0054] Step 1: Acquire images, use image magnification equipment to collect such as figure 2 The image of the semen sample shown, where the image magnification device is preferably a phase contrast microscope.

[0055] Step 2: Obtain the difference image, filter the bright spot area in the semen sample image, and obtain the difference image.

[0056] Step 2-1: Perform averaging processing on...

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. ...
