摘要
Apparatus and a concomitant method for estimating motion vectors having as an input a first image frame and a second image frame, each containing a plurality of pixels representing an image. The apparatus comprises: a pyramid processor for decimating a search area within the first image frame to produce a reduced resolution search area and for decimating a block of pixels in the second image frame to produce a reduced resolution pixel block; global search system for performing a global search within the reduced resolution search area using the reduced resolution pixel block until the reduced resolution pixel block substantially matches a matching block of pixels in the reduced resolution search area; and subsystem for computing an estimated motion vector representing a distance between a location of the reduced resolution pixel block within the second image frame and a location of the matching block of pixels within the first image frame.
