The images to be considered in this section are confined to scalar “mass-thickness contrast” images (see section 4.2 in Chapter 4). We decided to consider transform coding, generally based on the coding scheme proposed by Chen and Smith (1977), where a reversible linear transform is ...
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...
Block Transform In subject area: Computer Science A block transform is a technique used in image and speech coding that involves dividing an image or speech signal into sub-images and independently coding each sub-image. However, at low bit rates, this technique can result in a "blocking" ...
Transform coding is commonly used in image processing algorithms to provide high compression ratios, often at the expense of processing time and simplicity of the system. We have recently proposed a pixel value prediction scheme in order to exploit adjacent pixel correlation, providing a low-complexit...

Symmetry allows symmetric extension when dealing with image boundaries. Orthogonality leads to independent subimages. A higher number of vanishing moments results in a system capable of representing higher-degree polynomials with a small number of terms, which translates into better coding performance. ...
