Spatiotemporal Statistics for Video Quality Assessment

IEEE Transactions on Image Processing, 2016
It is an important task to design models for universal no-reference video quality assessment (NR-VQA) in multiple video processing and computer vision applications. However, most existing NR-VQA metrics are designed for specific distortion types, which are not often aware in practical applications.

Perceptual Video Quality Metric for 3D video quality assessment

2010 3DTV-Conference: The True Vision - Capture, Transmission and Display of 3D Video, 2010
One method of evaluating the quality of stereoscopic video is the use of conventional two dimensional (2D) objective metrics. Metrics with good representation of the Human Visual System (HVS) will present more accurate evaluation. In this paper we propose a perceptual based objective metric for 2D videos for 3D video quality evaluation.

Automatic gastroscopy video quality assessment

2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014
Automatic endoscope video analysis is an essential function for medical robot and computer-aided diagnosis system. However, the performance of these video analysis algorithms are often degraded by low quality endoscope images under the uncontrolled environment, where some of them are difficult even for human ourselves for analysis, such as over ...

Foveated video quality assessment

IEEE Transactions on Multimedia, 2002
Most image and video compression algorithms that have been proposed to improve picture quality relative to compression efficiency have either been designed based on objective criteria such as signal-to-noise-ratio (SNR) or have been evaluated, post-design, against competing methods using an objective sample measure.

Research on Video Quality Assessment

Journal of Multimedia, 2012
Objective quality assessment plays a very important role in the video applications, as they promise the means to evaluate the performance of acquisition, display, coding and communication systems. Objective video quality assessment still has a long way to go before it reaches the level of success. Perception video sequences quality metrics are of great

Software for video quality assessment

2016 39th International Conference on Telecommunications and Signal Processing (TSP), 2016
This paper deals with objective video assessment methods. The paper begins with a short introduction to video quality evaluation methods. Mainly it is concentrated to common objective measurement methods including Peak to Signal Noise Ratio (PSNR), Structural Similarity (SSIM), and Mean-Singular Value Decomposition (M-SVD).
