Patent ID: 8446964

Claim:
A method for the reduction of noise in a current video block, said method comprising: in a motion compensated temporal filter (MCTF), generating for the current video block a plurality of candidate motion vectors and a plurality of respective confidence values, wherein the confidence values provide an indication of accuracy of each of the candidate motion vectors in a prediction process involving a reference block; selecting one of the candidate motion vectors based on an evaluation of the confidence values, the one of the candidate motion vectors associated with a first confidence value; generating a first motion compensated block though application of the selected motion vector to a first reference block; and filtering the current video block and the first motion compensated block according to the first confidence value to generate a current filtered block, the filtering comprising: scaling the current video block according to a first scaling value; scaling the first motion compensated block according to a second scaling value; and combining the current video block with the first motion compensated block, wherein the first and second scaling values are based on the first confidence value.
