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 ...

Abstract With the growing demand for image and video-based applications, requirements of consistent quality assessment metrics video have increased. Different approaches been proposed in literature to estimate perceptual images videos. These can be divided into three main categories; full reference (FR), reduced (RR) no-reference (NR). In RR methods, instead providing original or as a reference...

The paper presents the methodology for 3D video subjective quality evaluation. Described methodology was designed to compare different 3D video compression technologies without an influence of any particular displaying or rendering technology. In addition detailed step by step description of test session design and preparation is provided. Experimental results for state-of-the-art 3D encoders a...

Three-dimensional (3D) video service is expected to be introduced as a next-generation television service. Stereoscopic video is composed of two 2D video signals for the left and right views, and these 2D video signals are encoded. Video quality between the left and right views is not always consistent because, for example, each view is encoded at a different bit rate. As a result, the video qu...

background: end stage renal disease negatively affects the patients’ quality of life. there are different educational methods to help these patients. this study was performed to compare the effectiveness of self-care education in two methods, face to face and video educational, on the quality of life in patients under treatment by hemodialysis in education-medical centers in urmia. methods: in ...

The file size and picture quality are factors to be considered for streaming, storage and transmitting videos over networks. This work compares Cinepak, Intel, Microsoft Video and Indeo Codec for video compression. The peak signal to noise ratio is used to compare the quality of such video compressed using AVI codecs. The most widely used objective measurement by developers of video processing ...
