Objective evaluation of compressed video's temporal flickering
This paper proposes a new method to evaluate the temporal impairments of compressed video signals. The proposed algorithm is block based; each block in a given frame is first classified as stable or in motion with respect to its co-located blocks in the previous and next frames. For each in-motion block, a motion estimation process is used to find its best match. Then the flickering estimation is conducted over a 3D window involving the current block and its temporally co-located or best matched blocks of the previous and next frames. The temporal quality is finally deduced from the flickering estimation. Simulation results show the efficacy of our algorithm.
