Digital video has become ubiquitous in our everyday lives; everywhere we look, there are
devices that can display, capture, and transmit video. The recent advances in technology …

The newly developed HEVC video coding standard can achieve higher compression
performance than the previous video coding standards, such as MPEG-4, H. 263 and H …

Example techniques are described to determine transforms to be used during video
encoding and video decoding. A video encoder and a video decoder may select transform …

Techniques are described in which a decoder is configured to inverse quantize a first
coefficient block and apply a first inverse transform to at least part of the inverse quantized …

Techniques are described in which a decoder is configured to reorganize a first 2-
dimensional coefficient block as a first 1-dimensional coefficient vector according to a …

A video coding device (eg, a video encoder or a video decoder) is configured to perform
various transformations on video data. The video coding device applies a primary transform …

In this letter, we provide a theoretical analysis of optimal predictive transform coding based
on the Gaussian Markov random field (GMRF) model. It is shown that the eigen-analysis of …

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 …
