Abstract:
1. A method for interpolating an intermediate frame block from (i) a previous frame block and (ii) a current frame block, the method comprising: processing the previous frame block by a first process; processing the previous frame block also by a second process different than the first process; calculating a first candidate motion vector as a function of (i) the current frame block, and (ii) the previous frame block processed by the first process; calculating a second candidate motion vector from (i) the current frame block, and (ii) the previous frame block processed by the second process; calculating a quality value for each of the first candidate motion vector and the second candidate motion vector, wherein the quality value indicates accuracy of the respective candidate motion vector in depicting object motion from the previous frame to the current frame; selecting, based on the quality value corresponding to each of the first candidate motion vector and the second candidate motion vector, a final motion vector from among the first candidate motion vector and the second candidate motion vector; and generating the intermediate frame block based on the final motion vector.
