METHOD FOR DETECTING SKIN REGION AND DEVICE FOR DETECTING SKIN REGION

摘要

A method and a device for detecting a skin region. The method comprises: obtaining a target image (101); obtaining a preset mean value and a preset standard deviation of the skin in an RGB color space, and a preset mean value and a preset standard deviation of the skin in a YUV color space (102); calculating a first probability for each pixel in the target image on the basis of the preset mean value and the preset standard deviation in the RGB color space, the first probability being the probability of the pixel being skin in the RGB color space (103); calculating a second probability for each pixel in the target image on the basis of the preset mean value and the preset standard deviation in the YUV color space, the second probability being the probability of the pixel being skin in the YUV color space (104); and determining the probability of being skin for each pixel in the target image, wherein the probability of the pixel being skin is the arithmetic mean value of the first probability and second probability of the pixel (105). The method and device are capable of automatically detecting the skin region in an image.
