  • Method and system for fast dense stereoscopic ranging
    Patent number: 8929645
    Abstract: A stochastic method and system for fast stereoscopic ranging includes selecting a pair of images for stereo processing, in which the pair of images are a frame pair and one of the image is a reference frame, seeding estimated values for a range metric at each pixel of the reference frame, initializing one or more search stage constraints, stochastically computing local influence for each valid pixel in the reference frame, aggregating local influences for each valid pixel in the reference frame, refining the estimated values for the range metric at each valid pixel in the reference frame based on the aggregated local influence, and post-processing range metric data. A valid pixel is a pixel in the reference frame that has a corresponding pixel in the other frame of the frame pair. The method repeats n iterations of the stochastically computing through the post-processing.

  • System and method for visually tracking with occlusions
    Patent number: 8611591
    Abstract: Described herein are tracking algorithm modifications to handle occlusions when processing a video stream including multiple image frames. Specifically, system and methods for handling both partial and full occlusions while tracking moving and non-moving targets are described. The occlusion handling embodiments described herein may be appropriate for a visual tracking system with supplementary range information.
