Snakehead egg counting method based on image processing

Abstract

The invention discloses a snakehead egg counting method based on image processing, and the method comprises the following steps: S1, carrying out the image collection of snakehead egg targets needing to be counted, and transmitting the image to a computer; s2, carrying out graying processing on the acquired image; s3, carrying out image enhancement by adopting a top-hat transformation algorithm, firstly designing a circular structure element, carrying out opening operation on the image, and subtracting the image obtained by the opening operation from the original image to realize an enhancement effect; s4, performing image filtering processing by adopting a guided filtering method; s5, carrying out image segmentation; and S6, identifying and counting eggs. According to the invention, the snakehead eggs are directly imaged to obtain the pictures of the snakehead eggs, the ovum counting task is completed on the non-contact premise through the processing flow provided by the invention, the precision is high, and the original living environment of the ovum cannot be changed.

Description

technical field [0001] The invention relates to the cross field of image processing and aquaculture, in particular to a method for counting snakehead eggs based on image processing. Background technique [0002] Snakehead is large in size, grows fast, and is rich in nutrients. It contains higher protein than chicken and beef. As a medicine, it has the effects of removing blood stasis, promoting regeneration, nourishing and recuperating, etc., so the breeding of snakehead has high economic value. Snakeheads mostly inhabit the muddy bottom of lakes, ponds, and rivers where the water is not smooth and turbid, and their spawning grounds are often in such places. The estimation of spawning time and amount of eggs is conducive to the artificial breeding in the later stage. [0003] There are four routine methods for counting the eggs of snakehead snakeheads. The most primitive method is direct counting, but it is time-consuming, especially for the large number of industrial see...

AI Technical Summary

Problems solved by technology

[0004] Generally speaking, there are two main problems in the traditional counting method of snakehead eggs. One is that in addition to manual direct counting, the traditional counting method, area method, volumetric method, and weighing method are all contact counting methods, which need to fish for eggs and destroy the original eggs. environment; secondly, because these methods use the method of estimating the area, volume or weight, and then dividing them equally, there must be certain errors due to individual differences, which are difficult to eliminate
