Image Processor Comprising Gesture Recognition System with Object Tracking Based on Calculated Features of Contours for Two or More Objects

摘要

An image processing system comprises an image processor having image processing circuitry and an associated memory. The image processor is configured to implement an object tracking module. The object tracking module is configured to obtain one or more images, to extract contours of at least two objects in at least one of the images, to select respective subsets of points of the contours for the at least two objects based at least in part on curvatures of the respective contours, to calculate features of the subsets of points of the contours for the at least two objects, to detect intersection of the at least two objects in a given image, and to track the at least two objects in the given image based at least in part on the calculated features responsive to detecting intersection of the at least two objects in the given image.
