Implement VoIP Based IP Telephony with Open Source Asterisk Architecture

Asterisk is a leading open source telephony software/system, easily implemented over intranet and internet. Asterisk empowers developers and integrators to create advanced communication solutions. An Asterisk system is a low cost type of a traditional PBX system. Any phone controlled by an Asterisk system can call a VoIP or analog phone controlled or managed by a traditional telephone system or...

Objective Video Quality Assessment

Digital video data, stored in video databases and distributed through communication networks, is subject to various kinds of distortions during acquisition, compression, processing, transmission, and reproduction. For example, lossy video compression techniques, which are almost always used to reduce the bandwidth needed to store or transmit video data, may degrade the quality during the quanti...

Objective assessment of MPEG-2 video quality

The increasing use of video compression standards in broadcasting television systems has required, in recent years, the development of video quality measurements that take into account artifacts specifically caused by digital compression techniques. In this paper we present a methodology for the objective quality assessment of MPEG video streams by using circular backpropagation feedforward neu...

Objective quality assessment for compressed video

We propose a new objective quality metric for evaluating image and video quality in coding application. In this metric, visual quality scores are given based on a combination of three factors: visually masked error, blurring distortion and structural distortion. Compared with vision-based model, it is easier to calculate and applicable to image and video processing application. Good correlation...

Content-aware objective video quality assessment

Since the end-user of video-based systems is often a human observer, prediction of user-perceived video quality (PVQ) is an important task for increasing the user satisfaction. Despite the large variety of objective video quality measures (VQMs), their lack of generalizability remains a problem. This is mainly due to the strong dependency between PVQ and video content. Although this problem is ...
