Embodiment Construction
[0051] In this embodiment, a gesture recognition method of Chinese Pule sign language encoding includes: 1. First capture the gesture action video of Chinese Pule sign language encoding with a camera to obtain a frame-by-frame RGB image sequence; 2. Perform color space conversion on each frame of image And determine the gesture area; 3 determine the fitting circle according to the minimum value of the extracted gesture edge contour point sequence, and replace the palm area, and then detect the fingertip and finger root; 4 take the center of the circle and the vertically downward unit vector as the standard, Extract the angle and distance features of each contour point; 5 use the dynamic time warping algorithm to map and transform the features to obtain the similar distance features of a certain gesture; 6 use a variety of classifiers to recognize sign language actions.
[0052] In this embodiment, in order to verify the effect of the present invention on recognizing Chinese Pul...
