Patent ID: 7424157

Claim:
An image data processing system comprising: in a digital processor, an identification process member identifying and extracting salient components in a given image data, wherein the given image data is a sequence of video frames, and the identification process member identifying and extracting a foreground object in the sequence of video frames; and a prioritizer responsive to the identification process member and prioritizing processing of the given image data, including for higher priority parts of the given image data, analyzing the highest priority parts in a manner which results in relatively more concise representations than that of lower priority parts, wherein the relatively more concise representations provide reduction in at least one of: computational processing, transmission bandwidth and storage requirement of the given image data, the prioritizer (a) applying motion estimation to the identified and extracted foreground object in multiple video frames, resulting in multiple motion estimates, and (b) integrating the resulting motion estimates into a higher order motion model which enables compact representation of pel data corresponding to the foreground object.
