We develop a tone-mapping operator (TMO) that considers the perceptual quality of the tone-mapped image together with the compression efficiency. The proposed TMO is formulated as an optimization problem that incorporates statistical models of i) the quality of the tone-mapped image given a desired TMO, ii) the base layer bit-rate and iii) the enhancement layer bit-rate. The results show that our...
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...
Multiview video coding is an emerging application where, in addition to classical temporal prediction, an efficient disparity prediction should be performed in order to achieve the best compression performance. A popular coder is the multiview video coding (MVC) extension of H.264/AVC, which uses a block-based disparity estimation (just like temporal prediction in H.264/AVC). In this paper, we propose...
