Abstract
In an coder for producing a bitstream representative of a sequence of video images, a previous image is registered with a current image using spline-based registration to produce estimated motion vectors. The estimated motion vectors are used to match blocks of the previous image and the current image to produce translation vectors. The translation vectors compensate for motion while encoding the sequence as a bitstream.
