Techniques for efficiently tracking points on a depth map using an optical flow are disclosed. In order to optimize the use of optical flow, isolated regions of the depth map may be tracked. The sampling regions may comprise a 3-dimensional box (width, height and depth). Each region may be “colored” as a function of depth information to generate a “zebra” pattern as a function of depth data for each sample. The disclosed techniques may provide for handling optical flow tracking when occlusion occurs by utilizing a weighting process for application of optical flow vs. velocity prediction to stabilize tracking.
