Abstract
The flickering effect is a serious problem of intra-only coding and is caused by different accuracy loss of transform coefficients by the quantization process from frame to frame. Nevertheless, the study for its solution has never been sufficient. In this paper, we analyze why flickering effect happens and illustrate our results of observation using intra-only coding scheme of the H.264/AVC standard. Based on our analysis, we propose a flickering effect reduction scheme which is a pre-processing method using the Kalman filtering algorithm. Simulation results show that the proposed scheme increases subjective visual quality by removing flickering effect.
