PCT No. PCT/SE92/00219 Sec. 371 Date Oct. 8, 1993 Sec. 102(e) Date Oct. 8, 1993 PCT Filed Apr. 3, 1992 PCT Pub. No. WO92/19068 PCT Pub. Date Oct. 29, 1992A block matching method for estimating motion contents in a video signal is presented. The motion is represented by a two-dimensional motion vector field, including horizontal and vertical vector components. The method can be used in a wide range of applications, has high spatial and motion vector resolution, is robust under adverse signal conditions, and is cost effective in real-time implementations. The block matching method includes iterative processing with different block sizes from coarse to fine with prediction of motion vectors from surrounding blocks. Resolution of each iteration's block size is preserved at the same resolution as the original input video signal for which the motion vector field is being generated. |
