Abstract
A system and method of providing motion estimation is disclosed. A recursive motion estimation module works in conjunction with a non-recursive motion estimation module to provide candidate motion vectors to a selection module. The selection module determines which of the candidates is more likely to yield a desirable result and selects that candidate accordingly.
Claims22
A method of providing motion estimation, the method comprising:
- estimating a first motion vector for a first block in a frame of video using a non-recursive motion estimation technique;
- estimating a second motion vector for the first block in the frame of video using a recursive motion estimation technique;
- determining an error metric corresponding to the first motion vector and the second motion vector;
- and
- selecting the motion vector having the better error metric among the first motion vector and the second motion vector.
