Reduced-Reference Video Quality Assessment of Compressed Video Sequences
IEEE Transactions on Circuits and Systems for Video Technology, 2012In this paper, a novel reduced-reference (RR) video quality assessment (VQA) is proposed by exploiting the spatial information loss and the temporal statistical characteristics of the interframe histogram. From the spatial perspective, an energy variation descriptor (EVD) is proposed to measure the energy change of each individual encoded frame, which ...

Proceedings. IEEE International Conference on Multimedia and Expo, 2003
There has been an increasing need recently to develop objective quality measurement techniques that can predict perceived video quality automatically. This paper introduces two video quality assessment models. The first one requires the original video as a reference and is a structural distortion measurement based approach, which is different from ...

No-reference quality assessment of highly compressed video sequences
2013 IEEE 15th International Workshop on Multimedia Signal Processing (MMSP), 2013In this paper we present a no-reference quality assessment algorithm for highly compressed H.264 videos. By analyzing the spatio-temporal artifacts and their effect on perceived visual quality we produced an array of viable predictors of quality. Using a feature selection method a small sub-set of features, each applied to a specific artefact-domain ...

A full reference stereoscopic video quality assessment metric
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017We propose a full reference stereo video quality assessment algorithm for assessing the perceptual quality of natural stereo videos. We exploit the separable representation of motion and binocular disparity in the visual cortex and develop a four stage algorithm to measure the quality of a stereoscopic video called FLOSIM3D.

Reduced-reference perceptual quality assessment for video streaming
2015 IEEE International Conference on Image Processing (ICIP), 2015We propose a perceptual video quality monitoring metric for streaming applications using the optical flow features. This approach is a reduced-reference pixel-based and relies only on the deviation of the optical flow of the corrupted frames. This techniques compares an optical flow descriptor from the corrupted frame against the descriptor obtained ...

A no-reference video quality assessment metric based on ROI
SPIE Proceedings, 2015A no reference video quality assessment metric based on the region of interest (ROI) was proposed in this paper. In the metric, objective video quality was evaluated by integrating the quality of two compressed artifacts, i.e. blurring distortion and blocking distortion.

Deep Neural Networks for No-Reference Video Quality Assessment
2019 IEEE International Conference on Image Processing (ICIP), 2019Video quality assessment (VQA) is a challenging task due to the complexity of modeling perceived quality characteristics in both spatial and temporal domains. A novel no-reference (NR) video quality metric (VQM) is proposed in this paper based on two deep neural networks (NN), namely 3D convolution network (3D-CNN) and a recurrent NN composed of long ...

No-reference video quality assessment via feature learning
2014 IEEE International Conference on Image Processing (ICIP), 2014In this paper, we propose a novel “Opinion Free” (OF) No-Reference Video Quality Assessment (NR-VQA) algorithm based on frame-level unsupervised feature learning and hysteresis temporal pooling. The system consists of three components: feature extraction with max-min pooling, frame quality prediction and temporal pooling. Frame level features are first

Efficient Full-Reference Assessment of Image and Video Quality
2007 IEEE International Conference on Image Processing, 2007Automatic quality assessment of digital pictures is a crucial issue in several image and video processing applications including broadcasting, archiving, or restoration. The visibility of impairments related to digital image processing systems is subject to the spatio-temporal properties of the given image or video content.

Full-reference video quality assessment on high-definition video content
2012 6th International Conference on Signal Processing and Communication Systems, 2012The paper provided herein aims at investigating two state-of-the-art publicly available full-reference video quality assessment metrics, particularly with regard to high-definition video data. Concretely, we will concentrate on the performance of the Multi-Scale Structural Similarity index (MS-SSIM) and the NTIA General Video Quality Metric (VQM ...
