Motion compensation can be performed by either "forward-acting" or "backward-acting" motion detection. Forward algorithms require the transmission of motion vectors, whereas backward algorithms estimate the motion from two previously reconstructed fr

The Max quantizer is a well-known algorithm for accomplishing efficient approximate representation of analog samples from a signal source by using values taken from a finite set of allowed values when the probability density function of the source is
