In this context, efficient objective quality assessment of 3D video is a critical demand, in particular for real world applications. Recent objective 3D video quality assessment methods are based on availability of the original (reference) video as well as utilizing depth map information of video frames. In this paper, we study the efficacy of using robust features extracted from 3D stereoscopic video, to propose a no-reference (NR) video quality assessment (VQA) model. The extracted features included; motion vector lengths and depth map information of 3D stereoscopic video frames. The proposed quality metric, entitled MD-QA, was tested on EPFL 3D stereoscopic video database and compared to full-reference (FR) objective quality assessment methods. The performance evaluation of MD-QA was achieved by applying it over original and compressed videos with three types of compression techniques such as MPEG1, MPEG2 and H264/AVC. Based on the experimental results, MD-QA metric demonstrates an efficient and accurate quality measure of 3D stereoscopic videos under H264/AVC compression.","PeriodicalId":294036,"journal":{"name":"2015 7th Computer Science and Electronic Engineering Conference (CEEC)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123829581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we analyze a proposed live 3D video streaming system that transmits a 3D live video through a wireless LAN network (WLAN). The live 3D video is captured from the Kinect RGB-D sensor, then a 3D point cloud is being generated and processed. Several filters are applied during preprocessing stage which handles the spatial redundancy, then before streaming an Octree compression is used to further reduces the temporal redundancy. In this paper a color based conditional filter is designed to reduce color information for each frame. The filter condition is defined using the mean and the standard deviation of the occurrences in the color histogram. The quality of the whole system which includes filtering, compression and streaming is evaluated using several measurements: compression ratio, total bytes per points, peak signal to noise ratio (PSNR) and Similarity Structure index (SSIM). The experimental results shows that the proposed system have a best PSNR of 14dB and SSIM 81% with compression ratio of 10.69% while the best compression ratio is about 12% with PSNR 12.05dB of and SSIM 78.64%.","PeriodicalId":294036,"journal":{"name":"2015 7th Computer Science and Electronic Engineering Conference (CEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115747243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
