Maximizing Subjective Quality for Scalable Video Coding
With the upcoming scalable video coding algorithms as a solution to the problem of increasing heterogeneity in devices and networks, new challenges arise regarding the subjective quality towards the end user. Scalable video coding allows on-the-fly adaptation of the different aspects of visual quality, taking into account the expectations of the user. In this paper, we propose a machine learnin...
متن کاملAn Improvement Method of Subjective Picture Quality within Concerned Regions for H.264 Video Coding
Video compression is very crucial method which is used to reduce the quantity of data used to represent digital video pictures. However, most video compression is loss when the video pictures data is quantized. So a quantizer is key factors for adjusting the bitrate and controlling the picture quality. Importantly, if the concerned region of video sequence takes on high level picture quality, t...
متن کاملSubjective Quality Metric for 3D Video Services
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...
متن کاملMethodology for 3D Video Subjective Quality Evaluation
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...
متن کاملCQA - Subjective Video Codec Quality Analyser
A subjective video codec quality analyser (CQA) has been designed and implemented. It was specified to take two video streams as input: the original, uncompressed, stream and the compressed/decompressed stream. The CQA compared the subjective quality of the coded stream with respect to the uncoded one by computing the values of a number of factors designed to assess artefacts that were subjecti...
