Abstract: A method and system for detecting and tracking hands in an image. The method for detecting and tracking hands in an image comprises 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.

Abstract: Systems and methods for rendering an entertainment animation. The system can comprise a user input unit for receiving a non-binary user input signal; an auxiliary signal source for generating an auxiliary signal; a classification unit for classifying the non-binary user input signal with reference to the auxiliary signal; and a rendering unit for rendering the entertainment animation based on classification results from the classification unit.
