Title: METHOD FOR TRACKING FINGER CONTOURS AND APPARATUS THEREOF
Abstract:
A method and corresponding apparatus for tracking finger contours, the method comprising: acquiring a depth image and a colour image of the same image recording the hand of a user (S1); extracting the outer contour of the hand from the depth image or the colour image (S2); using the finger web of the outer contour of the hand as a segmentation point for segmenting the finger part, segmenting the outer contour of the hand and acquiring an initial outer contour of each finger part (S3); for the outer contour of each finger part, combining the initial outer contour of the finger part in order to constrain the outer contour of the finger part to adhere to the edges corresponding to the finger part in the colour image and acquire the tracked outer contour of the finger part (S4). The present invention can accurately track the outer contours of a finger part.
