چکیده

We introduce a new research tool – the LIVE Mobile Video Quality Assessment (VQA) database. The database consists of pristine reference and distorted videos, along with human/subjective opinion scores of the associated video quality. The database was designed towards improving our understanding of human judgements of time-varying video quality in heavilytrafficked wireless networks. A byproduct of a better understanding could be quantitative models useful for the development of perceptually-aware algorithms for resource allocation and rate adaptation for video streaming. The database consists of 200 distorted videos created from 10 RAW HD videos acquired using a RED ONE digital cinematographic camera. It includes static distortions such as compression and wireless packet loss, as well as dynamically varying distortions. We describe the creation of the database, simulated distortions and the human study that we conducted to obtain 5,300 time-sampled subjective traces of quality and summary subjective scores. We analyze the results obtained for certain subclasses of distortions from this large database of interest in context of wireless video delivery. The LIVE Mobile VQA database, including the human subjective scores, will be made available to researchers in the field at no cost in order to aid the development of novel strategies for videoaware resource allocation.

In-capture Mobile Video Distortions: A Study of Subjective Behavior and Objective Algorithms

Digital videos often contain visual distortions that are introduced by the camera hardware or processing software during the capture process. These distortions often detract from a viewer’s quality of experience. Understanding how human observers perceive the visual quality of digital videos is of great importance to camera designers. Thus, the development of automatic objective methods that ac...

A Machine Learning Approach to No-Reference Objective Video Quality Assessment for High Definition Resources

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

A Subjective and Objective Study of Stalling Events in Mobile Streaming Videos

Over-the-top mobile adaptive video streaming is invariably influenced by volatile network conditions, which can cause playback interruptions (stalling or rebuffering events) and bitrate fluctuations, thereby impairing users’ quality of experience (QoE). Video quality assessment models that can accurately predict users’ QoE under such volatile network conditions are rapidly gaining attention, si...
