Adaptive block tree structure for video coding
ETRI Journal, 2020 The Joint Video Exploration Team (JVET) has studied future video coding (FVC) technologies with a potential compression capacity that significantly exceeds that of the high‐efficiency video coding (HEVC) standard.

Edge-Based Coding Tree Unit Partitioning Strategy in Inter Prediction [PDF]
, 2014 The High Efficiency Video Coding standard increases in the range of [30, 40] % data compression ratio compared to H.264/MPEG-4 (AVC), but it requires bigger number of operations. HEVC uses a quadtree coding structure. The quadtree partitioning process is a high complexity operation since it employs an exhaustive process, called rate distortion ...

Gravitational tree-code on graphics processing units: implementation in CUDA
Procedia Computer Science, 2010 We present a new very fast tree-code which runs on massively parallel Graphical Processing Units (GPU) with NVIDIA CUDA architecture. The tree-construction and calculation of multipole moments is carried out on the host CPU, while the force calculation which consists of tree walks and evaluation of interaction list is carried out on the GPU.

The Number of Huffman Codes, Compact Trees, and Sums of Unit Fractions
IEEE Transactions on Information Theory, 2013 The number of "nonequivalent" Huffman codes of length r over an alphabet of size t has been studied frequently. Equivalently, the number of "nonequivalent" complete t-ary trees has been examined. We first survey the literature, unifying several independent approaches to the problem.

CtuNet: A Deep Learning-based Framework for Fast CTU Partitioning of H265/HEVC Intra- coding
Ain Shams Engineering Journal, 2021 Nowadays, real-time multimedia applications mandate high video quality while maintaining reasonable bitrates. The H.264 coding delivered inexpensive bitrate costs compared to other coding schemes while maintaining high-grade video quality, yet bounded to

Efficient H.264-to-HEVC Transcoding Based on Motion Propagation and Post-Order Traversal of Coding Tree Units [PDF]
IEEE Transactions on Circuits and Systems for Video Technology, 2018 In this paper, we propose a fast H.264-to-HEVC transcoder composed of a motion propagation algorithm and a fast mode decision framework. The motion propagation algorithm creates a motion vector candidate list at the coding tree unit (CTU) level and, thereafter, selects the best candidate at the prediction unit level.

A Progressive Universal Noiseless Coder [PDF]
, 1994 The authors combine pruned tree-structured vector quantization (pruned TSVQ) with Itoh's (1987) universal noiseless coder. By combining pruned TSVQ with universal noiseless coding, they benefit from the “successive approximation” capabilities of TSVQ ...

An Adaptive Quad-Tree Depth Range Prediction Mechanism for HEVC
IEEE Access, 2018 A next-generation video coding standard High Efficiency Video Coding (HEVC) provides higher video quality and lower compression bit rate but leads to very high encoding complexity, especially in the quad-tree-based coding tree unit partitioning process ...

Speed Up VVC Intra-Coding by Learned Models and Feature Statistics
IEEE Access, 2023 The newest video coding standard, Versatile Video Coding (VVC), adopts a QTMT, quad-tree plus multi-type tree (MTT), block partition structure and improves the compression performance by about 30% ${\sim }50$ %, compared with the previous ...
