The moving object is captured by two cameras during time. A robust curve stereo matching algorithm is employed to extract the precise location of some singular-points for any sequence. The motion of object is estimated by tracking these points and a large number of cameras can be constructed for the moving object during time. Finally, the silhouette cones of all virtual cameras are intersected to extract the fine visual hull. In the proposed method, the quality of reconstruction is improved by fusing the advantages of silhouette, motion and stereo. Because of using the curve matching scheme instead of color matching, our method is less sensitive to color adjustment between cameras and illumination changes of light source. Our method is applicable also to the low-texture object","PeriodicalId":267577,"journal":{"name":"2006 IEEE Workshop on Multimedia Signal Processing","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133806395","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}

For the particular application to superresolution, downsampling properties derived in the DCT domain are exploited to add structure to the learning algorithm.

The MVC pattern is based on a clear separation of objects into three categories, i.e. model for defining and maintaining data, view for rendering interactions based on the data, and controller for coordinating actions and events that affect the model and view(s). As part of our layered multimodal dialog system architecture, this synchronization module in our approach controls the synchronization of multiple modalities, such as speech, mouse and keyboard, by interpreting XML document that incorporates SMIL and EMMA. It isolates dialog model from complex presentations associated with different channels and user interfaces through the adoption of a generic object binding mechanism. These flexibilities lead to enhanced design freedom in multimodal dialog system architecture that supports client based, sever based and distributed solutions","PeriodicalId":267577,"journal":{"name":"2006 IEEE Workshop on Multimedia Signal Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122115693","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}

Julius is open source CSR software, and has been used by many researchers and developers in Japan as a standard decoder on PCs. Julius works as a real time decoder on a PC. However further computational reduction is necessary to use Julius on a microprocessor. Further cost reduction is needed. For reducing cost of calculating pdfs (probability density function), Julius adopts a GMS (Gaussian mixture selection) method. In this paper, we modify the GMS method to realize a continuous speech recognizer on microprocessors. This approach does not change the structure of acoustic models in consistency with that used by conventional Julius, and enables developers to use acoustic models developed by popular modeling tools. On simulation, the proposed method has archived 20% reduction of computational costs compared to conventional GMS, 40% reduction compared to no GMS. Finally, the embedded version of Julius was tested on a developmental hardware platform named \"T-engine\". The proposed method showed 2.23 of RTF (real time factor) resulting 79% of that of no GMS without any degradation of recognition performance","PeriodicalId":267577,"journal":{"name":"2006 IEEE Workshop on Multimedia Signal Processing","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116627500","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}

A well known wavelet based scalable coding scheme for single-view video sequences has been adopted and extended to match the specific needs of scalable multi-view video coding. Motion compensated temporal filtering (MCTF) is applied to each video sequence of each camera. The use of a wavelet lifting structure guarantees perfect invertibility of this step, and as a consequence of its open-loop architecture, SNR and temporal scalability are attained. Correlations between the temporal subbands of adjacent cameras are reduced by a novel disparity compensated view filtering (DCVF), method which is also lifting based and open-loop to enable view scalability. Spatial scalability and entropy coding are achieved by the JPEG2000 spatial wavelet transform and EBCOT coding, respectively. Rate allocation along the temporal-view-filtered subbands is done by means of an RD-optimal algorithm.

A solid block of 3D data can be constructed by arranging the images into a stack. This volume, also known as the epipolar-plane image volume, contains highly structured data that can be segmented for object removal, insertion and compression. In this paper, we propose a segmentation scheme that takes fully advantage of the known geometry in order to model occlusions explicitly as a result of disparity. Moreover, we include this knowledge into an energy minimization scheme based on region competition with active contours. Instead of extracting layers sequentially from front to back, each layer is made to compete with the regions it is going to occlude and the ones it is going to disocclude.
