Reduzierung der Bewegungsvektoren in Fernsehbildern. |
摘要 |
Apparatus for reducing the number of motion vectors associated with a digital television image comprises a vector filter (36), a vector calculator (37) and a vector processor (38, 39) for deriving for each block of pixels within the television image a plurality of motion vectors representing the most common motion vectors of pixels in the block, each of the plurality of motion vectors having associated with it a figure of merit based upon the weighted absolute difference of the motion vectors of pixels in the block, and a vector reducer (40) for associating with the plurality of motion vectors, a further motion vector for the same position from the previous field and a further motion vector for the same position from the next field, each of said further motion vectors having associated with it a figure of merit, and for selecting a smaller plurality of motion vectors from the plurality of motion vectors and the further motion vectors in dependence on the figures of merit. |
