Foreground Dectection of Yaks of Deep Color Based on Gray Images

Nowadays, foreground detection of digital images has been a heated topic in visual researches of computer graphics and has had great significance in a variety of areas in our society. Digital image foreground extraction is also called image cutout, the important part of computer image processing technology, is also the basis of graphic image processing algorithm. The foreground extraction of digital image refers to dividing an image into two parts of the scene region and the background region, and at the same time the foreground image is extracted form a new image. In this paper, yaks are extracted and displayed in yak images in the Three Rivers Source area of Qinghai province. Plenty of experiments show that the dark-colored yak foreground extraction algorithm in this paper has a good effect on yak foreground recognition. The results of this study can provide an algorithm basis for yak intelligent weight analysis.
