The local decoded picture is basically used as the reference for inter-picture prediction to avoid the mismatch between encoding and decoding. However, the coding efficiency is not necessarily the optimal in this processing. In this report, we try to use the original picture as the reference. In this case, the mismatch causes degradation of the picture quality. However, the bit amount will be reduced. To take optimal coding, we propose the adaptive method based on the bit amount and the decoded picture error. The original picture is used only in the block which has less bit amount and small error increasing. We apply this coding to MPEG-4 Main Profile. As the results of experiments, about 0.2dB gain in PSNR is given in a sequence. It is recognized that the adaptive method works successfully and coding performance can be improved. |
