Decoupling and controlling independently these factors is a key step in many practical applications and in this work it is achieved by modeling the face manifold with a bilinear model. Bilinear modeling, however, can only be applied to vectors, and therefore a vector representation for each face is established first. To this end, we use a generic face model that is fitted to each face under the constraint that anatomical points get aligned. The effectiveness and applicability of the proposed method is demonstrated with an application to facial expression recognition.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065467","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 method starts with an initialization step where a small number of key frame pairs are selected to set up a global reference. Given a query image we automatically relate it to the existing key frames based on their pair-wise similarity evaluation. Four major enhancements are made in this step to achieve better performance. Firstly, a recently developed technique, SURF, is applied for robust feature detection. Secondly, an efficient coarse-to-fine matching strategy is implemented. Thirdly, an improved global representation is defined over each image for accurate and fast similarity evaluation. Finally, the method is constantly updated by adding more query images. Experiments were carried out to evaluate the performances of image self-organization by using a large number of images captured from our university's campus.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127459315","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}

First, individuals concepts are modeled independently. Second, an ontology is introduced via the representation of the relationship between concepts and the ontological readjustment of the confidence values. Our contribution lies in the manner in which inter-concepts similarities are exploited in the indexing system using co-occurrence, visual descriptors, and hybrid semantic similarities. Experimental results report the efficiency and the significant improvement provided by the proposed scheme.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125474890","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}

We present an alternate approach that extrapolates a method for enmasse audience interaction through video. The enmasse interaction simulates a particle moving in the field of motion created by the audience, and the audience interacts by manipulating the particle position. In this paper, we show that by adding sets of constraints to the particle motion, one can build GUI-style widgets. We describe several of these widgets and the results of a small-sample pilot study to test them. The results are not conclusive, but are encouraging, suggesting possibilities for video games and interactive theatre.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116996615","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 system runs retrieval on multi-level transcriptions (word and phone) produced by word and phone recognizers respectively, and their outputs are combined. We propose to use latent Dirichlet allocation (LDA) model for capturing the semantic information on word transcription. The LDA model is employed for estimating topic distribution in queries and word transcribed spoken documents, and the matching is performed at the topic level. Acoustic matching between query words and phonetically transcribed spoken documents is performed using phone-based matching algorithm. The results of acoustic and topic level matching methods are compared and shown to be complementary.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127728523","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 present a new fusion method based on HSI (Hue-Saturation-Intensity) and Contourlet transform. First, we convert the multispectral image from the RGB color space into the HSI color space. Then, by applying Contourlet transform to the panchromatic image and the I component of the multispectral image, we utilize an improved fusion rule based on PCA for the low-frequency sub-images, and engage the maximum fusion rule for the high-frequency sub-images. Finally, a fusion image is obtained by the inverse HSI transform. The experimental results show that the proposed fusion method not only enhances the spatial resolution of the fusion image, but also preserves the spectral information of the original multispectral image.","PeriodicalId":233839,"journal":{"name":"2009 10th Workshop on Image Analysis for Multimedia Interactive Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128274837","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}
