HUMAN HAND DETECTION METHOD AND DEVICE BASED ON SKIN COLOUR

摘要

Provided is a human hand detection method based on a skin colour. The method comprises: converting an acquired image to be detected from an RGB colour space into an HSV colour space to acquire an HSV image, and converting the image to be detected from the RGB colour space into an r-g colour space to acquire an r-g image; converting the HSV image into a first binary image, and converting the r-g image into a second binary image; performing a bitwise AND operation on the first binary image and the second binary image so as to obtain a comprehensive binary image; filtering the comprehensive binary image to acquire an optimized binary image; analysing a maximum connected region in the optimized binary image, and taking the maximum connected region as a skin region; using a pre-trained K neighbour classifier to determine whether the maximum connected region is in a hand shape, thereby realizing human hand recognition. The method has a rapid detection speed, and effectively avoids the human hand error detection in gesture recognition.
