ABSTRACT:
Some embodiments of the invention provide a method of performing motion estimation for an array of image values obtained from a current image. The method starts with an initial estimate of the motion of the current image. The method then determines whether the initial estimate of the motion of the current image array between the current image and a reference image is acceptable. If not, the method specifies a first value for a parameter for performing the motion estimation. Otherwise, the method specifies a second value for the parameter. The method then performs a motion estimation operation based on the specified value of the parameter. One example of a specified parameter is the size of the window that the motion estimation operation uses. Another example is the starting level for a hierarchical motion estimation operation that it performs. A hierarchical motion estimation operation searches the reference frame at several different levels of granularity.
