Image Processor Configured for Efficient Estimation and Elimination of Foreground Information in Images

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 a foreground processing module utilizing the image processing circuitry and the memory. The foreground processing module is configured to obtain one or more images, to estimate a foreground region of interest from the one or more images, to determine a plurality of segments of the foreground region of interest, to calculate amplitude statistics for respective ones of the plurality of segments, to classify respective segments as being respective portions of static foreground objects or as being respective portions of dynamic foreground objects based at least in part on the calculated amplitude statistics and one or more defined patterns for known static and dynamic objects, and to remove one or more segments classified as static foreground objects from the foreground region of interest.

1. A method comprising the steps of:
obtaining one or more images; estimating a foreground region of interest from the one or more images; determining a plurality of segments of the foreground region of interest; calculating amplitude statistics for respective ones of the plurality of segments; classifying respective segments as being respective portions of static foreground objects or as being respective portions of dynamic foreground objects based at least in part on the calculated amplitude statistics and one or more defined patterns for known static and dynamic objects; and removing one or more segments classified as static foreground objects from the foreground region of interest; wherein the steps are implemented in an image processor comprising a processor coupled to a memory.
