Copyright information of video contents is manually extracted for the secondary use of those contents, and its cost is highly expensive. Therefore, automatic detection of credit titles that contain copyright information is highly demanded. However, accuracy of conventional methods is usually insufficient for this purpose. Our method first estimates credit-title-superimposed region based on character density distribution calculated in advance by using many video contents. Then, credit titles are detected in the estimated region. The experiment results show that proposed method improves both recall and precision rates compared to a conventional method. Furthermore, the processing time of the proposed method is less than half that of the conventional method for all contents.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123099597","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}

HYBRID TCP/UDP video transport for H.264/AVC content delivery in burst loss networks 突发丢失网络中H.264/AVC内容传输的HYBRID TCP/UDP视频传输

When implementing the hybrid approach, we argue that the playback at the receiver often need not be 100% perfect, provided that a certain level of quality is assured. Reliable TCP is used to transmit and guarantee delivery of the most important packets. This allows use of additional features in the H.264/AVC standard which simultaneously provide an enhanced playback quality, in addition to a reduction in throughput. These benefits are demonstrated through experimental results using a test-bed to emulate the hybrid proposal. We compare the proposed system with other protection methods, such as FEC, and in one case show that for the same bandwidth overhead, FEC is unable to match the performance of the hybrid system in terms of playback quality. Furthermore, we measure the delay associated with our approach, and examine its potential for use as an alternative to the conventional methods of transporting video by either TCP or UDP alone.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124376606","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}

Supervised signer adaptation must utilize the labeled adaptation data that are collected explicitly. To skip the data collecting process in signer adaptation, we propose an unsupervised adaptation method called hypothesis comparison guided cross validation (HC-CV) algorithm. The algorithm not only addresses the problem of overlap between the data set to be labeled and the data set for adaptation, but also employs an additional hypothesis comparison step to decrease the noise rate of the adaptation data set. Experimental results show that the HC-CV adaptation algorithm is superior to the CV adaptation algorithm and the conventional self-teaching algorithm. Though the algorithm is proposed for signer adaptation, it can also be applied to speaker adaptation and writer adaptation straightforwardly.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123084854","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 video is recorded by a gaze-directed camera, which can actively directs at the visual attention area from the person who wears the camera. Here we present a method based on the combination of 2D and 3D hand model, which can estimate the position of hand in image accurately and the pose of hand in 3D roughly. The method uses 2D model tracking result to initialize and predict 3D tracking, which saves the number of particles and makes it possible for local configuration adapting. To evaluate our result, we try our algorithm on several pieces of video both from normal camera and gaze-directed camera. The error ratio of the distance between the ground truth and tracking result is used as an objective measurement for evaluating our method. Trajectory of hand movement and results of projected model for every frame show that our method is effective and makes a good foundation for future recognition and analysis.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117209231","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 proposed architecture mainly consists on a coarse grain systolic array obtained by replicating a unique and homogeneous Functional Unit (FU), in which a whole Deblocking-Filter unit is implemented. The proposal is also based on a novel macroblock-level parallelization strategy of the filtering algorithm which improves the final performance by exploiting specific data dependences. This way communication overhead is reduced and a more intensive parallelism in comparison with the existing state-of-the-art solutions is obtained. Furthermore, the architecture is completely flexible, since the level of parallelism can be changed, according to the application requirements. The design has been implemented in a Virtex-5 FPGA, and it allows filtering 4CIF (704x576 pixels @30fps) video sequences in real-time at frequencies lower than 10.16 Mhz.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120904777","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}

While a large number of discriminant analysis algorithms have been proposed in recent years, most of them consider an equal importance of each training sample and ignore the different contributions of these samples to learn the discriminative feature subspace for classification. Motivated by the fact that some training samples are more effectual in learning the low-dimensional feature space than other samples, we propose using different weights to characterize the different contributions of the training samples and incorporate such weighting information into the popular maximum margin criterion algorithm to devise the corresponding AMMC for image classification. Moreover, we extend the proposed MMC algorithm to the semi-supervised case, namely, semi-supervised adaptive maximum margin criterion (SAMMC), by making use of both labeled and unlabeled samples to further improve the classification performance. Experimental results are presented to demonstrate the efficacy of the proposed methods.","PeriodicalId":433997,"journal":{"name":"2011 IEEE International Conference on Multimedia and Expo","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127218127","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 describe a new approach to integrate interactive services provided by an AmI environment with the television set, which is one of the most used interaction client in the home environment. An implementation of this approach has been carried out as a multimodal/multipurpose natural human computer interface for elderly people, by creating adapted graphical user interfaces and navigation menus together with multimodal interaction (simplified TV remote control and voice interaction). In addition, this user interface can also be suited to other user groups. We have tested a prototype that adapts the videoconference and the information service with a group of 83 users.
