Video quality is an intuitional and efficient guideline for quality of service of the whole communication system and quality of experience from the end users' viewpoint. In this paper, we present a no reference video quality assessment metric using inter-frame redundancy of video sequences. Human eyes are adapted to extract useful information from viewed video, so we determine these regions of ...

End-to-end quality of service for real-time video delivery over ATM networks depends on both video coding and network performance. Historical measures of QoS for data services have involved packet delivery parameters such as cell loss and delay, but these are not directly representative of a user's perception of the delivered video quality. To this end, this paper describes the use of a video q...

introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...

We sought to develop and deploy a video-based smartphone-delivered mobile HIV Risk Reduction (mHIVRR) intervention to individuals in an addiction treatment clinic. We developed 3 video modules that consisted of a 10-minute HIVRR video, 11 acceptability questions, and 3 knowledge questions and deployed them as a secondary study within a larger study of ecological momentary and geographical momen...

Due to rapid advance of various video applications and services, such as video telephony, mobile video broadcasting, and Internet Protocol television (IPTV), there is an increasing demand for accurate and effective quality assessment of underlying videos. Accurate video quality assessment is crucial to video codec development, network protocol planning, in-network quality monitoring, quality as...

Medical images and videos are now increasingly part of modern telecommunication applications, including telemedicinal applications, favored by advancements in video compression and communication technologies. Medical video quality evaluation is essential for modern applications since compression and transmission processes often compromise the video quality. Several state-of-the-art video qualit...

Advances in multimedia devices, video compression efficiency and increased availability of network bandwidth have increased the proliferation of multimedia applications. However, the proliferation of these applications has also increased the need to maximize available network resources and also meet end users’ Quality of Experience (QoE) and expectations. We present results for end-to-end video...
