It can predict the residue of motion compensated prediction (MCP) using the additional derived disparity vector. However, its coding performance depends on the accuracy of disparity vector derivation. In this paper, we propose the improved disparity vector derivation scheme for ARP. In the proposed scheme, the disparity vector is derived from the corresponding block in the reference picture. And that corresponding block is pointed by the same as MCP. Moreover, the disparity vector can be derived not only from the current reference block, but also from the blocks on the all other reference pictures included in the current reference picture lists. In addition, the disparity vector can be derived from both of the blocks predicted by disparity compensated prediction (DCP) and the blocks predicted by MCP and ARP because the derived disparity vector for ARP is stored in additional disparity vector field. Experimental results show that 0.2% bitrate reduction of synthesized views, and up to 0.5% for each dependent views in the reference software of 3D-HEVC.","PeriodicalId":166978,"journal":{"name":"2014 IEEE Visual Communications and Image Processing Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115606292","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}

Most existing research on information security such as cryptography and steganography is mainly concerned about transmission and yet little has been done to prevent the information displayed on screens from reaching eyes of the bystanders. This \"security of the last foot (SOLF)\" problem, if left without being taken care of, will inevitably lead to the total failure of a trustable information communication system. To deal with the SOLF problem, for the application of text-reading, we proposed an eye tracking based solution using the newly revealed concept of uncrowded window from vision research. The theory of uncrowded window suggests that human vision can only effectively recognize objects inside a small window. Object features outside the window may still be detectable but the feature detection results cannot be efficiently combined properly and therefore those objects will not be recognizable. We use eye-tracker to locate fixation points of the authorized reader in real time, and only the area inside the uncrowded window displays the private information we want to protect. A number of dummy windows with fake messages are displayed around the real uncrowded window as diversions. And without the precise knowledge about the fixations of the authorized reader, the chance for bystanders to capture the private message from those surrounding area and the dummy windows is very low. Meanwhile, since the authorized reader can only read within the uncrowded window, detrimental impact of those dummy windows is almost negligible. The proposed prototype system was written in C++ with SDKs of Direct3D, Tobii Gaze SDK, CEGUI, MuPDF, OpenCV and etc. Extended demonstration of the system will be provided to show that the proposed method is an effective solution to SOLF problem of information communication and display.","PeriodicalId":166978,"journal":{"name":"2014 IEEE Visual Communications and Image Processing Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116755016","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}
