Embodiment Construction

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0046] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] Such as figure 1 As shown, the method for counting yak based on video data provided by the embodiment of the present invention includes the following steps:

[0048] S101: Obtain high-resolution image data of the yak when it is released;

[0049] S102: Perform average filtering on the image, and adopt a pyramid structure;

[0050] S103: Use the image data at the top of the pyramid as the data source and grayscale the image to perform a histogram equalization operation;

[0051] S104:...

Abstract

The invention belongs to the technical field of information automation, and discloses a yak counting method based on video data. The yak counting method includes the steps of obtaining high-resolution image data of yaks going out of lairs, conducting mean value filtering for the images, constructing a pyramid structure, using the pyramid top image data as a data source to gray the images, conducting histogram equalization, using a sobel gradient operator to conduct convolution filtering for the images, marking connected domains for the filtered images, extracting the suspected target areas, extracting the area characteristics, establishing a characteristic space, determining whether the areas are yak areas by on-line shape prediction indexes, area gray value standard deviation, the color mean values of the area gray scales and the Bayesian classifier based on minimal classification error rate criteria, and using the area growth algorithm for compensation, thereby effectively improving the algorithmic counting performance. The method effectively solves the problem of counting yaks, and reduces the time and labor cost.

Description

Technical field [0001] The invention belongs to the technical field of information automation, and particularly relates to a method for counting yaks based on video data. Background technique [0002] "Yak Technology Software Based on Video Data" At present, yak breeding is still in the development stage in my country's animal husbandry industry. Its development greatly affects the economic level of my country's animal husbandry industry, especially for the Tibetan areas of my country, which are dominated by the Qinghai-Tibet Plateau. Livestock breeding. For a long time, my country’s yak breeding has been dominated by primitive and wild grazing. The Tibetan herders in Tibetan areas regard yak as a precious material wealth and foundation, so every household has kept a large number of yaks for a long time, ranging from two to two. There are hundreds to three hundred, and as many as thousands. In order to clarify the number of yaks in the family, it is extremely important for herder...
