Spatiotemporal Adaptive Quantization for the Perceptual Video Coding of RGB 4:4:4 Data
Lee Prangnell, Victor Sanchez
Due to the spectral sensitivity phenomenon of the Human Visual System (HVS), the color channels of raw RGB 4:4:4 sequences contain significant psychovisual redundancies; these redu…
Spatiotemporal Adaptive Quantization for Video Compression Applications
Lee Prangnell
JCT-VC HEVC HM 16 includes a Coding Unit (CU) level adaptive Quantization Parameter (QP) technique named AdaptiveQP. It is designed to perceptually adjust the QP in Y, Cb and Cr Co…
Frequency-Dependent Perceptual Quantisation for Visually Lossless Compression Applications
Lee Prangnell
The default quantisation algorithms in the state-of-the-art High Efficiency Video Coding (HEVC) standard, namely Uniform Reconstruction Quantisation (URQ) and Rate-Distortion Optim…
Adaptive Quantization Matrices for HD and UHD Display Resolutions in Scalable HEVC
Lee Prangnell, Victor Sanchez
HEVC contains an option to enable custom quantization matrices, which are designed based on the Human Visual System and a 2D Contrast Sensitivity Function. Visual Display Units, ca…
