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...
This paper presents an adaptive search range selection based on prediction error and local statistics of the neighboring blocks. The performance, computation, and power consumption of block matching motion estimation algorithms in video coding standards depends on the motion search range. An optimal search range for each block is determined on the basis of motion vectors and prediction errors obtained...
