Abstract
A method for depth mapping includes receiving an image of a pattern of spots that has been projected onto a scene, which includes a hand having fingers. The image is processed in order to segment and find a three-dimensional (3D) location of the hand. Based on the spots appearing on the hand in the 3D location, a first depth value that is characteristic of the hand and a second depth value that is characteristic of a background of the scene behind the hand are computed. The spots in a vicinity of the hand in the image between the first and second depth values are sorted in order to extract separate, respective contours of each of the fingers. The respective contours are processed in order to identify a posture of the hand and fingers.
