Cross-component linear model (CCLM) for chroma intra-prediction is a promising coding
tool in the joint exploration model (JEM) developed by the Joint Video Exploration Team …

The Discrete Cosine Transform (DCT), and in particular the DCT type II, has been widely
used for image and video compression. Although DCT efficiently approximates the optimal …

Throughout the past few decades, the separable discrete cosine transform (DCT),
particularly the DCT type II, has been widely used in image and video compression. It is well …

As 3D scanning devices and depth sensors advance, dynamic point clouds have attracted
increasing attention as a format for 3D objects in motion, with applications in various fields …

In this paper, we present a DCT/DST based transform scheme that applies either the
conventional DCT or type-7 DST for all the video-coding intra-prediction modes: vertical …

Many new DCT-like transforms have been proposed since the first edition of this book. For
example, the integer DCT that yields integer transform coefficients, the directional DCT to …

Google started an opensource project, entitled the WebM Project, in 2010 to develop
royaltyfree video codecs for the web. The present generation codec developed in the WebM …

In many state-of-the-art compression systems, signal transformation is an integral part of the
encoding and decoding process, where transforms provide compact representations for the …
