Abstract

The invention belongs to the technical field of information automation, and discloses a method for counting yaks based on video data, which includes: acquiring high-resolution image data of yaks when they come out of the market; performing mean value filtering on the images, and adopting a pyramid structure; using the top layer of the pyramid The image data is used as the data source, and the image is grayscaled, and the histogram equalization operation is performed; the sobel gradient operator is used to perform convolution filtering on the image; the connected domain is marked on the filtered image, and the suspected target area is extracted; the features of the area are extracted , establish the feature space; online prediction shape index, standard deviation of regional gray value, color mean of regional gray value and Bayes classifier based on minimum classification error rate criterion to judge whether it is a yak region; use region growing algorithm to compensate it, Effectively improve the counting performance of the algorithm. The invention effectively solves the problem of counting the number of yaks, and reduces the required time cost and labor cost.

Description

technical field [0001] The invention belongs to the technical field of information automation, and in particular 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, and its development greatly affects the economic level of my country's animal husbandry, especially for the Tibetan areas dominated by the Qinghai-Tibet Plateau. Livestock breeding. For a long time, yak breeding in my country has been dominated by primitive rough grazing. Tibetan herdsmen in Tibetan areas regard yaks as precious material wealth and foundation, so every household has kept a large number of yaks for a long time. Hundreds to three hundred, up to thousands. In order to find out the number of yaks at home, it is very important for herdsmen. For a long time, many herdsmen drive the cattle to the pens or roadway circles, and surro...
