Abstract |
In this paper, we propose an analysis of the residual information of the HEVC. We focus specifically on analyzing the coding of the DC coefficient and its effect on bit consumption. We investigate on the possibilities and the limits of coding the DC coefficient, in a lossless coding way, by changing the process to the encoding a spatial translation value or the residual blocks instead of the transform/quantization process. Experimental results show that 8 bits can be approximated as the limit of DC bit cost of a lossless coding, under which we may obtain a gain in the BD-rate. |
