Skeletonization and template matching-based traffic police gesture identification method

The invention discloses a skeletonization and template matching-based traffic police gesture identification method, which comprises the following steps of: (1) extracting key gestures of a traffic police, performing binarization on gesture sequence images, and normalizing the size of the binary images; (2) extracting the image outline of the key gestures of the traffic police, performing skeletonization by adopting outline deletion to obtain skeletons of the key gesture images of the traffic police, and storing the skeletons corresponding to various key gestures of the traffic police in a template library; and (3) extracting the key image of the current traffic police gesture sequence, performing skeletonization by adopting outline deletion to obtain the current gesture skeleton, matchingthe current gesture skeleton and each skeleton in the template library to find the most similar skeleton serving as the current traffic police gesture skeleton, and obtaining identification results of traffic police fingers.
