Hou, Yonghong and Wang, Pichao and Xiang, Wei and Gao, Zhimin and Hou, Chunping (2015) A novel rate control algorithm for video coding based on fuzzy-PID controller. Signal, Image and Video Processing , 9 (4). pp. 875-884. ISSN 1863-1703


Rate control algorithms (RCAs) aim to achieve the best visual quality under the minimum bit rate and the limited buffer size. A self-parameter-tuning fuzzy-PID controller is proposed to reduce the deviation between the target buffer level and the current buffer fullness. Fuzzy logic is used to tune each parameter of the proportional-integral-derivative controller by selecting appropriate fuzzy rules through simulation in H.264/advanced video coding (AVC). To control the quality fluctuation between consecutive frames, a quality controller is adopted. The proposed RCA has been implemented in an H.264/AVC video codec, and our experimental results show that the proposed algorithm achieves smooth target bits while enabling better buffer control and visual quality.
