To efficiently transmit H.264/AVC coded video over error prone channel, an end-to-end rate distortion optimized motion estimation is proposed. The end-to-end pixel level distortion of transmitted frame is estimated at the encoder, and then the distortion of reference frame area is weighted and combined with the conventional Lagrangian cost of motion estimation to form an enhanced cost function. By...
A partition-level adaptive sub-pixel interpolation filter method for video coding is proposed in this paper. Various type of interpolation filters are exploited to compensate the limited motion accuracy represented by motion vector or improve interpolation performance of directional textures inconsistent with motion direction, an optimal filter is selected as sub-pixel interpolation filter for each...
