A deep learning scheme named Deep Blind Video Quality Assessment (DeepBVQA) is proposed to achieve a more accurate and reliable video quality predictor by considering various spatial and temporal cues which have not been considered before.
Abstract
The high performance video quality assessment (VQA) algorithm is a necessary skill to provide high quality video to viewers. However, since the nonlinear perception function between the distortion level of the video and the subjective quality score is not precisely defined, there are many limitations in accurately predicting the quality of the video. In this paper, we propose a deep learning scheme named Deep Blind Video Quality Assessment (DeepBVQA) to achieve a more accurate and reliable video quality predictor by considering various spatial and temporal cues which have not been considered before. We used CNN to extract the spatial cues of each video in VQA and proposed new hand-crafted features for temporal cues. Performance experiments show that performance is better than other state-of-the-art no-reference (NR) VQA models and the introduction of hand-crafted temporal features is very efficient in VQA.

Spatial and Temporal Contrast-Sensitivity Functions of the Visual System

TL;DR: In this paper, the reciprocal nature of these spatio-temporal interactions can be particularly clearly expressed if the threshold contrast is determined for a grating target whose luminance perpendicular to the bars is given by where m is the contrast, v the spatial frequency, and ƒ the temporal frequency of the target.
