DCT and DST Filtering with Sparse Graph Operators
Keng-Shih Lu, Antonio Ortega, Debargha Mukherjee +1
Graph filtering is a fundamental tool in graph signal processing. Polynomial graph filters (PGFs), defined as polynomials of a fundamental graph operator, can be implemented in the…
Study On Coding Tools Beyond Av1
Xin Zhao, Liang Zhao, Madhu Krishnan +5
The Alliance for Open Media has recently initiated coding tool exploration activities towards the next-generation video coding beyond AV1. With this regard, this paper presents a p…
A Technical Overview of AV1
Jingning Han, Bohan Li, Debargha Mukherjee +12
The AV1 video compression format is developed by the Alliance for Open Media consortium. It achieves more than 30% reduction in bit-rate compared to its predecessor VP9 for the sam…
Perceptually inspired weighted MSE optimization using irregularity-aware graph Fourier transform
Keng-Shih Lu, Antonio Ortega, Debargha Mukherjee +1
In image and video coding applications, distortion has been traditionally measured using mean square error (MSE), which suggests the use of orthogonal transforms, such as the discr…
