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. To deal with the 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 the problem of information security and display.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128340970","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}

There is an obvious drawback of DLPP that it only considers the pairwise geometric relationship of samples. However, in many real-world issues, relationships among the samples are often more complex than pairwise. Naively squeezing the complex into pairwise ones will inevitably lead to loss of some information, which are crucial for classification and clustering. We address this issue via using the Hyper-Laplacian instead of the regular Laplacian in DLPP, which only can depict the pairwise relationship. This new DLPP algorithm is exactly a generalization of DLPP and we name it Discriminant Hyper-Laplacian Projection (DHLP). Five popular face databases are adopted for validating our work. The results demonstrate the superiority of DHLP over DLPP, particularly in face recognition in the wild.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128715884","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}

The framework targets at improving the reconstruction quality of the depth images, especially in edge areas. In a typical 3DV system, depth images are used for synthesizing the virtual views, therefore preserving high quality depth images, especially the edge information is important. However, the ringing artifacts may be introduced at the depth edge areas due to the compression distortion of the depth images. The SEOC framework resolves this problem, after reconstruction, by identifying each edge pixel and enhancing it of the full depth image with values coded in the bitstream. Experimental results demonstrate that, compared with the original 3D-HEVC, the proposed algorithm can achieve about 6% bitrate saving on average.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124453780","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}

The most essential issues for pattern recognition include extracting discriminant features and improving recognition accuracy. Kernel Entropy Component Analysis (KECA), as a new method for data transformation and dimensionality reduction, has attracted more attentions. However, as KECA only reveals structure relating to the Renyi entropy of the input space data set, it cannot extract effectively discriminant classification information for recognition. In this paper, we propose combining KECA and Fisher's linear discriminant analysis (LDA), utilizing descriptor of information entropy and scatter information of classes to improve recognition performance. The proposed method is applied to speech-based emotion recognition, and evaluated though experiments on RML audiovisual emotion databases. The results clear demonstrate the effectiveness of the proposed solution.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117188149","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}

The stability of content information is more reliable than user contributed context information, which was ignored by many existing methods. In this paper, through discovering the latent feature space between visual features and context, we propose a novel approach for social image retrieval by imposing context regularization terms to constraint visual features. The method can effectively reflect the interior visual structure for social image representation. Experimental results on the NUS-WIDEOBJECT dataset demonstrate that the proposed approach obtains competitive performance compared with state-of-the-art methods.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122032555","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}

Therefore, this paper introduces a technique named Multi-directional SKIP and DIRECT modes (MDSD) to ameliorate SKIP/DIRECT mode to adapt to the features of block motion. Based on the study of the correlation between spatial adjacent blocks with the same or different motion models, a priority-based motion information derivation method is designed. A higher priority is assigned to the motion information of neighboring blocks with the same motion model as current block. Experiments in AVS2 reference software RD3.0 show improvements of up to 3.9% in BD rate reduction are achieved.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132612032","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}

With the rapid development of stereoscopic display techniques, stereoscopic saliency detection is much desired for the emerging stereoscopic applications. Compared with 2D saliency detection, the depth factor has to be considered in stereoscopic saliency detection. Inspired by the wide applications of machine learning techniques in 2D saliency detection, we propose to use the machine learning technique for stereoscopic saliency detection in this paper. The contrast features from color, luminance and texture in 2D images are adopted in the proposed framework. For the depth factor, we consider both the depth contrast and depth degree in the proposed learned model. Additionally, the center-bias factor is also used as an input feature for learning the model. Experimental results on a recent large-scale eye tracking database show the better performance of the proposed model over other existing ones.","PeriodicalId":178700,"journal":{"name":"2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126081631","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}
