Abstract:
1. A method for providing reliable motion vectors, comprising: determining, with a processor, motion vectors between a first image frame and a second image frame with backward and forward estimation, the first image frame preceding the second image frame; comparing, with the processor, backward estimation motion vectors and forward estimation motion vectors; detecting, with the processor, unreliable motion vectors based on a comparison result; determining, with the processor, image background regions covered by an object and image background regions left uncovered by the object based on unreliable motion vectors; removing, with the processor, the unreliable motion vectors; and replacing, with the processor, removed unreliable motion vectors with reliable, predetermined background motion vectors, wherein an unreliable motion vector is detected by the image background regions covered by the object and the image background regions left uncovered by the object are determined by
