摘要
Disclosed are a hand positioning method and a human-computer interaction system. The method comprises a step of continuously capturing a current image so as to obtain a sequence of video images; a step of extracting a foreground image from each of the captured video images, and then carrying out binary processing so as to obtain a binary foreground image; a step of obtaining a vertex set of a minimum convex hull of the binary foreground image, and then creating areas of concern serving as candidate hand areas; and a step of extracting hand imaging features from the respective created areas of concern, and then determining a hand area from the candidate hand areas by carrying out pattern recognition based on the extracted hand imaging features.
