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 8):
A method according to  claim 2  in which initial candidate motion vectors are derived from motion estimation applied to overlapping rectangular image blocks, with an overlap structure in which each pixel not close to a picture edge occupies four regions; and, an assignment process allocates refined motion vectors to pixels in dependence on respective error values for the refined motion vectors.
