Image
& Video Quality Assessment at LIVE
The Quality
Assessment research at LIVE is being conducted in collaboration
with CPS
Introduction
to Image and Video Quality Assessment
LIVE Databases for Image
and Video Quality Assessment
Objective Quality Assessment Research
at LIVE
- No-Reference
Quality Assessment
Distortion-agnostic and distortion-specific blind image quality
assessment based on natural scene statistics in the wavelet
and DCT domains.
- Full-Reference
Quality Assessment:
Information theoretic methods, structural similarity based image
quality assessment and foveated image quality index.
- Video Quality Assessment Research
at LIVE
On-going video quality assessment research at LIVE includes
development of algorithms for objective video quality assessment,
as well as the
LIVE mobile VQA database, that will complement the LIVE IQA
and VQA databases.
