COME for No-Reference Video Quality Assessment
2018 IEEE Conference on Multimedia Information Processing and Retrieval (MIPR), 2018Nowadays, the issue of objective Video Quality Assessment (VQA) has been extensively studied. In this paper, we present an effective general-purpose VQA method named COnvolutional neural network and Multi-regression based Evaluation (COME). It requires no referred lossless video and is universal for non-specific types of distortion.

Video Quality Assessment in the DASH Technique
2019 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2019The paper presents video quality assessment issues that include different methods. A subjective video quality assessment of the MPEG-4 / H.264 encoded clips, at the selected bitrates and picture resolutions, is shown. The authors underline the necessity of using a subjective approach to complement objective methods and propose the measurement scenario ...

Quality Assessment of Virtual Reality Videos
2019360-degree spherical images/videos, also called virtual reality (VR) images/videos, can provide an immersive experience of real scenes in some specific systems. This makes it widely used in VR games, sporting events and VR movies. However, due to its high resolution, it is so difficult to transmit, compress or store VR images/videos.

No-Reference Video Shakiness Quality Assessment
2017Video shakiness is a common problem for videos captured by hand-hold devices. How to evaluate the influence of video shakiness on human perception and design an objective quality assessment model is a challenging problem. In this work, we first conduct subjective experiments and construct a data-set with human scores.

Framework for the integrated video quality assessment
Multimedia Tools and Applications, 2011Through years of development Content Networks (CN) have become more sophisticated and more technically diverse. Modern CN are designed to be more adaptive to communication environment, devices and user requirements. However, one open issue is the still fluctuating quality of service provision. As a result user experience can be negatively affected.

Fast Video Registration Method for Video Quality Assessment
2004In this paper, we propose a block-based video registration method that can be used for various applications such as objective video quality assessment. Instead of using the entire frames of a reference video sequence and a processed video sequence, we use a limited number of frames which are selected under a certain criterion and the selected frames ...
