Reference and reference failures [PDF]

open access: yesProceedings of the 1987 workshop on Theoretical issues in natural language processing -, 1987
Introduction Reference in the real world differs greatly from the reference processes modelled in current natural ~ language systems. A speaker in the real world is a rational agent who must make a decision about his description in a limited time, with limited resources, knowledge, and abilities.

NoR-VDPNet++: Real-Time No-Reference Image Quality Metrics

open access: yesIEEE Access, 2023
Efficiency and efficacy are desirable properties for any evaluation metric having to do with Standard Dynamic Range (SDR) imaging or with High Dynamic Range (HDR) imaging. However, it is a daunting task to satisfy both properties simultaneously.

Review of Research on Video Quality Assessment Based on Deep Learning

open access: yesJisuanji kexue yu tansuo, 2021
Video quality assessment (VQA) is based on the subjective quality assessment results of the human eye, using models to evaluate distorted videos. It is difficult for traditional assessment methods to make subjective assessment results consistent with ...
