1. A motion estimation method, comprising:
- selecting a plurality of first selected motion vectors from a plurality of candidate motion vectors according to dissimilarity of the candidate motion vectors; and
determining a target motion vector corresponding to a minimum block matching cost according to the first selected motion vectors without referring to each non-selected motion vector remaining in the candidate motion vectors.

Abstract
A motion estimation method includes selecting a plurality of selected motion vectors from a plurality of candidate motion vectors according to dissimilarity/priorities of the candidate motion vectors and determining a target motion vector corresponding to a minimum block matching cost according to the selected motion vectors without referring to each non-selected motion vector remaining in the candidate motion vectors.
