Abstract
A method and apparatus for motion vector estimation for a plurality of image frames including retrieving a reference hash value associated with a reference frame, wherein the reference hash value represents a spatially oriented block of pixels, generating a plurality of image hash values including a first hash value for a first area represented by a spatially oriented block of pixels of an image frame and computing a motion vector estimate using a plurality of first hash values and the reference hash value is disclosed.
