Spatial-Temporal Residue Network Based In-Loop Filter for Video Coding
, 2017 Deep learning has demonstrated tremendous break through in the area of image/video processing. In this paper, a spatial-temporal residue network (STResNet) based in-loop filter is proposed to suppress visual artifacts such as blocking, ringing in video ...

Post-processing of transform coded images using selective filtering and fuzzy-based enhancement [PDF]
, 1997 Transform coding often leads to artifacts called blocking when the image or video is compressed to low bit-rate. In this paper, a new post-processing scheme using selective low-pass filtering and fuzzy-based enhancement is proposed.

Low-complexity lossless codes for image and video coding [PDF]
SPIE Proceedings, 2010 We describe design of lossless block codes for geometric, Laplacian, and similar distributions frequently arising in image and video coding. Proposed codes can be understood as a generalization of Golomb codes, allowing more precise adaptation to values of parameters of distributions, and resulting in lower redundancy.

H.266/VVC fast intra prediction using Sobel edge features
Electronics Letters, 2021 Versatile video coding is the next‐generation video coding standard. Compared with the previous high efficiency video coding standard, versatile video coding reduces 30% or more bitrate but requires significantly higher encoding complexity.

A Discrete Tchebichef Transform Approximation for Image and Video Coding
, 2015 In this paper, we introduce a low-complexity approximation for the discrete Tchebichef transform (DTT). The proposed forward and inverse transforms are multiplication-free and require a reduced number of additions and bit-shifting operations.

Adaptive deblocking filter for transform domain Wyner-Ziv video coding [PDF]
, 2009 Wyner-Ziv (WZ) video coding is a particular case of distributed video coding, the recent video coding paradigm based on the Slepian-Wolf and Wyner-Ziv theorems that exploits the source correlation at the decoder and not at the encoder as in predictive ...

Steered mixture-of-experts for light field images and video : representation and coding [PDF]
, 2020 Research in light field (LF) processing has heavily increased over the last decade. This is largely driven by the desire to achieve the same level of immersion and navigational freedom for camera-captured scenes as it is currently available for CGI ...

Low-Complexity Loeffler DCT Approximations for Image and Video Coding
Journal of Low Power Electronics and Applications, 2018 This paper introduced a matrix parametrization method based on the Loeffler discrete cosine transform (DCT) algorithm. As a result, a new class of 8-point DCT approximations was proposed, capable of unifying the mathematical formalism of several 8-point ...
