METHOD AND SYSTEM FOR DETECTING AND TRACKING HANDS IN AN IMAGE
First Claim
1. A method for detecting and tracking hands in an image, the method comprising the steps of:
- calculating a first probability map comprising of probabilities that respective pixels in the image corresponds to skin based on colour information associated with the respective pixels;
calculating a second probability map comprising of probabilities that the respective pixels in the image corresponds to a part of a hand based on depth information associated with the respective pixels;
calculating a joint probability map by combining the first probability map and the second probability map; and
detecting and tracking hands in the image using an algorithm with a weight output as a detection threshold applied on the joint probability map.
