Residual-guided In-loop Filter Using Convolution Neural Network [PDF]
ACM Transactions on Multimedia Computing, Communications, and Applications, 2021 The block-based coding structure in the hybrid video coding framework inevitably introduces compression artifacts such as blocking, ringing, and so on. To compensate for those artifacts, extensive filtering techniques were proposed in the loop of video codecs, which are capable of boosting the subjective and objective qualities of reconstructed videos.

Multi-strand coronal loop model and filter-ratio analysis [PDF]
, 2009 We model a coronal loop as a bundle of seven separate strands or filaments. Each of the loop strands used in this model can independently be heated (near their left footpoints) by Alfv\'en/ion-cyclotron waves via wave-particle interactions.

GPU Parallelization of HEVC In-Loop Filters [PDF]
International Journal of Parallel Programming, 2017 In the High Efficiency Video Coding (HEVC) standard, multiple decoding modules have been designed to take advantage of parallel processing. In particular, the HEVC in-loop filters (i.e., the deblocking filter and sample adaptive offset) were conceived to be exploited by parallel architectures.
