OBJECT AND KEYPOINT DETECTION SYSTEM WITH LOW SPATIAL JITTER, LOW LATENCY AND LOW POWER USAGE

Abstract:

Video object and keypoint location detection techniques are presented. The system includes a detection system for generation locations of an object's keypoints along with probabilities associated with the locations, and a stability system for stabilizing keypoint locations of the detected objects. In some aspects, the generated probabilities are two-dimensional array correspond locations within input images, and stability system fits the generated probabilities to a two-dimensional probability distribution function.
