Elastic movement compensation of images involves determining motion vectors of main and sub-blocks by comparing blocks, sub-blocks with reference blocks, sub-blocks, using specific correction vectors

摘要

The method involves determining macro block motion vectors by determining the motion vector of a current image (7) main block by comparing the main block with reference main blocks of a reference image (8) with checked motion vectors in a defined main search area, dividing the current image into sub-blocks, determining the motion vectors of the sub-blocks by comparing the sub-blocks with reference sub-blocks and using specific correction vectors. Independent claims are also included for the following: a method of sharpening sharp-edged objects in an image, a method of constructing a high resolution image from a sequence of individual images, an arrangement for acquiring images and a computer program product for implementing an inventive method.
