Abstract
A system and method of providing motion estimation is disclosed. A recursive motion estimation module applies multiple recursive motion estimation rules which have complimentary performance advantages. A selection module provides a switching scheme which determines which rule to apply to a specific block within a video frame.
Claims25
A method of providing motion estimation between video frames in a device, the method comprising:
- receiving a first frame of a video;
- generating a first motion vector for a first block in the first frame of the video using a first recursive motion estimation rule from a predefined pattern alternating the first recursive motion estimation rule and a second recursive motion estimation rule;
- generating a second motion vector for a second block in the first frame of the video using the second recursive motion estimation from the predefined pattern alternating the first recursive motion estimation rule and the second recursive motion estimation rule;
- and
- determining a modified video from the video with the first motion vector and the second motion vector for displaying on a device.
