Rate Control for Slimmable Video Codec using Multilayer Perceptron

As a flexible design for practical end-to-end video compression, slimmable video coding achieves variable rate coding with an adaptable complexity. In this paper, rate control using a multilayer perceptron is proposed to achieve accurate bitrate control for slimmable video coding. An average bitrate error of less than 0.3% is achieved on tested sequences at a slight decrease in the rate-distortion performance. Furthermore, the results show that there is no overflow or underflow in the buffer occupancy during the rate control process.
