ABSTRACT:
The disclosed method provides a new resolution of the aperture problem, which is one of the basic problems present in motion estimation technology. The method constitutes a resolution of this problem by means of adaptive transfer to smaller blocks. The approach consists of adaptive partitioning of the picture with the use of quadratic trees. If an aperture problem is detected in the block, then the block partitions with the help of quadratic trees into smaller blocks. The partitioning continues until either the aperture problem is resolved or the smallest size block is reached. Through the use of this method, the aperture problem is successfully resolved without substantial loss in the degree of compression.
