Abstract:
In video motion estimation an initial candidate motion vector is generated for each block and a vector error is determined as for example a DFD. Spatial gradients of pixel values are calculated and used to refine the initial candidate motion vector. The relative contribution of the spatial gradients to the refinement process depends on the vector error.

Claim (Index 17):
In a video motion estimation system, a method for generating candidate motion vector fields that represent the respective positions of a frame's pixels in a respective reference frame, comprising the steps of:\n forming initial candidate motion vectors each having a respective vector error; forming spatial gradients of pixel values; and refining said initial candidate motion vectors in a refinement process to form candidate motion vectors for a subsequent motion vector assignment process; in which the contribution of said spatial gradients of pixel values to the refinement process is determined by said vector error; in which the contribution of pixels to the refinement process is determined by multiplication by a weight function which is a decreasing function of the vector error.
