Perceptual Quality Assessment of Video Considering Both Frame Rate and Quantization Artifacts
In this paper, we explore the impact of frame rate and quantization on perceptual quality of a video. We propose to use the product of a spatial quality factor that assesses the q...

Segmentation-driven perceptual quality metrics
We present a full-reference and a no-reference perceptual video quality metric that incorporate both low-level and high-level aspects of vision. Low-level aspects include color pe...

RFSIM: A feature based image quality assessment metric using Riesz transforms
Image quality assessment (IQA) aims to provide computational models to measure the image quality in a perceptually consistent manner. In this paper, a novel feature based IQA mode...
