+// 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.
