i.e., the coding tree. The CTB size may range from 8×8 to 64×64 luma samples, but typically 64×64 is used. Each CTB can be further split into smaller square blocks called coding blocks (CBs). After the CTB is split recursively into...
The researchers investigate the performance of different image transform coding schemes used in pre-processing, their comparison, and effectiveness, the necessary and sufficient conditions, properties and complexity in implementation. Whimsical by prior advancements in image processing techniques, the ...

The theoretical and practical aspects of transform coding systems for processing still or moving images are discussed. Among the specific topics considered are: the statistical properties of images; orthogonal transforms for image coding; and transform coefficient quantization and bit allocation. Some pract...
Compression of animated geometry using geometric transform coding A geometric transform coder encodes the residual between a transformed base mesh and the original mesh, for each of a series of meshes in a time dependent geometry stream. The geometric transform that matches the base mesh to the cur...

本文以HEVC(High-Efficiency Video Coding)和正在制定过程中的下一代VVC(Versatile Video Coding)标准为背景,阐述了二次变换技术在这两代国际视频压缩标准之间将近十年时间里的技术演进。 一、 二次变换技术 所谓二次变换,就是在主变换(Primary transform)之后对频域信号(主变换系数)进行第二次变换,将信号从一个变换...
Transform based image compression has difficulty with image regions containing edges. Edge compensated transform coding (ECTC) addresses this problem by preprocessing to remove edges. This preprocessing is adapted to transform coding. The edge information is sent in a side channel and the edges are re...
A transform matrix, in the context of Computer Science, refers to a matrix that is used to convert data from one coordinate system to another. It is a mathematical tool used in various applications, such as video coding schemes, to transform and process data efficiently. In this particular ca...
