LBP is often associated with changes in motor control. Some subgroups of LBP have been argued to have a compromised ability to dissociate lumbopelvic movement from that of the thoracolumbar junction. Clinical methods to evaluate this task may aid identification of this LBP subgroup and determine the utility of this information to guide clinical interventions. The study aimed to develop a clinic...

With more and more visual signals being received by human observers, an important aspect of the quality of experience of such stimuli is the perceived visual quality. In this thesis, new techiques to assess this perceived visual quality of natural videos without a pristine reference video, referred to as no-reference video quality assessment (NR-VQA), are presented, in order to evaluate the per...

This paper proposes an endpoint video combiner architecture in a multipoint control unit (MCU) system for high definition multiparty video conferencing. The proposed architecture addresses the current reliability, computational and quality drawbacks of a conventional centralized based video combiner architecture. This is achieved by redesigning the MCU video to move away the video combiner from...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Introduction: YouTube is a popular social media platform frequently searched by online users for retrieving health-related information. Pulmonary rehabilitation programs have an important place in the COVID-19 treatment protocols. The aim of this study was to evaluate pulmonary videos on YouTube.
 Methods: A total 180 tagged with search terms “COVID-19 rehabilitation”, exercise” and physio...

The rapid rise in popularity of multimedia applications, such as VoIP, IPTV and Video Conferencing, intensifies the need to consider resource management for user satisfaction. Furthermore, improving Quality of Experience (QoE) in Software Defined Networks (SDNs) services is one of the important issues to be addressed by provisioning optimum resource management. In this paper, resource allocatio...

Motion-JPEG is a common video format for compression of motion images with highquality using JPEG standard for each frame of the video. During transmission through a noisychannel some blocks of data are lost or corrupted, and the quality of decompression frames decreased.In this paper, for reconstruction of these blocks, several temporal-domain, spatial-domain, andfrequency-domain error conceal...
