Method for detecting skin region and apparatus for detecting skin region

A system for detecting a skin region in an image, comprising:

• one or more processors;
• and
• memory storing instructions, the instructions, when executed by the one or more processors, cause the processors to perform operations comprising:
• obtaining a target image;
• and
• for each of a plurality of pixels in the target image, calculating a probability that the pixel corresponds to skin captured in the image, wherein calculating the probability includes:
• calculating a first probability of said each pixel in the target image in a first color space the first probability being a probability that the pixel is skin in the first color space;
• calculating a second probability of said each pixel in the target image in a second color space that is distinct from the first color space, the second probability being a probability that the pixel is skin in the second color space;
• and
• determining a combined probability that said each pixel in the target image is skin, the combined probability that the pixel is skin being an arithmetic mean value of the first probability and the second probability of the pixel.

A non-transitory computer-readable storage medium for detecting a skin region in an image, the computer-readable storage medium storing instructions, the instructions, when executed by one or more processors, cause the processors to perform operations comprising:

• obtaining a target image;
• and
• for each of a plurality of pixels in the target image, calculating a probability that the pixel corresponds to skin captured in the image, wherein calculating the probability includes:
• calculating a first probability of said each pixel in the target image in a first color space the first probability being a probability that the pixel is skin in the first color space;
• calculating a second probability of said each pixel in the target image in a second color space that is distinct from the first color space, the second probability being a probability that the pixel is skin in the second color space;
• and
• determining a combined probability that said each pixel in the target image is skin, the combined probability that the pixel is skin being an arithmetic mean value of the first probability and the second probability of the pixel.
