// Multiframe Quality Enhancement.
// The aim for MFQE is to replace pixel blocks in the current frame with
// the correlated pixel blocks (with higher quality) in the last frame.
// The replacement can only be taken in stationary blocks by checking
// the motion of the blocks and other conditions such as the SAD of
// the current block and correlated block, the variance of the block
// difference, etc.
