In scal-able video coding, hierarchical MCTF is extensively adopted to exploit the temporal correlation across video frames. In this hierarchical MCTF structure, the strength of temporal correlation varies with the level of temporal trans-
Web24 de ago. de 2024 · In this paper, we take a step forward to video semantic compression and propose the Hierarchical Reinforcement Learning based task-driven Video Semantic Coding, named as HRLVSC. Specifically, to simplify the complex mode decision of video semantic coding, we divided the action space into frame-level and CTU-level spaces in … Web9 de ago. de 2016 · Rate control plays an important role in video coding for rectifying the coded bit stream to meet the transmission bandwidth, which is related to two parts of bit allocation and quantization parameter acquirement. Considering that the bit allocation is a critical step due to its effect on the subsequent coding operation and rate-distortion …
