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...
