Hierarchical fast motion vector estimation apparatus and method using average pyramid

摘要

The present invention relates to an apparatus and method for estimating a hierarchical fast motion vector using an average pyramid for fast computation processing and performance improvement of a block matching algorithm in interframe motion vector search in a moving image.;The present invention is composed of a layer 2, a layer 1, and a layer 0 motion vector generation unit 100, 200 and 300. In the layer 2 motion vector generation unit 100, a current (K) And transmits the generated first motion vector to the layer 1 block 200. [;The layer 1 motion vector generator 200 sets the first motion vector generated by the layer 1 block 100 as an initial value, generates a second motion vector through the data in the search range and the current frame from the initial value, Block 300 as shown in FIG.;Finally, the layer 0 motion vector generator 300 generates a third motion vector through the current frame and data in the search range from this initial value, which also sets the motion vector generated by the layer 1 block 200 as an initial value, do.
