Identifying high-level concepts, such as music mood, from this \"black-box\" representation is particularly challenging. Therefore we present in this paper a novel music representation that allows gaining an in-depth understanding of the music structure. Its principle is to decompose sparsely the music into a basis of elementary audio elements, called musical words, which represent the notes played by various instruments generated through a MIDI synthesizer. From this representation, a music feature is also proposed to allow automatic music classification. Experiments driven on two music datasets have shown the effectiveness of this approach to represent accurately music signals and to allow efficient classification for the complex problem of music mood classification.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125547286","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 introduce a two-step method that consists of performing supervised acoustic topic modeling on audio features followed by a classification process. Experimental results in classifying audio signals with respect to onomatopoeias and semantic labels using the BBC Sound Effects library show that the proposed method can improve the classification accuracy relatively 10~14% against the baseline supervised acoustic topic model. We also show that the proposed method is compatible with different labels so that the topic models can be trained with one set of labels and used to classify another set of labels.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129485165","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 recognition system is based on an original feature for sound event detection in real life. This feature, called ”spectral cover” shows an interesting behaviour to recognize water flow in a noisy environment. The system is only based on thresholds. It is simple, robust, and can be used on every corpus without training. An experiment is realized with more than 7 hours of videos recorded by a wearable device. Our system obtains good results for the water flow event recognition (F-measure of 66%). A comparison with classical approaches using MFCC or low levels descriptors with GMM classifiers is done to attest the good performance of our system. Adding the spectral cover to low levels descriptors also improve their performance and confirms that this feature is relevant.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114359675","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, a new approach to detect onboard camera shots in compressed Formula 1 video sequences is presented. To that end, and after studying the characteristics of the shot, a technique based in the thresholding comparison between a high motion area and a stationary one has been devised. Efficient computation is achieved by direct decoding of the motion vectors in the MPEG stream. The shot detection process is done through a frame-by-frame hysteresis thresholding analysis. In order to enhance the results, a SVD shot boundary detector is applied. Promising results are presented that show the validity of the approach.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122048760","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 popular implementation used by the community is the one in OpenCV. The detector shows its strong power in detecting faces, but we found it hard to be extended to other kinds of objects. The convergence of the training phase of this algorithm depends a lot on the training data. And the prediction precision stays low. In this paper, we have come up with new ideas to improve its performance for diverse object categories. We incorporated six different types of feature images into the Viola and Jones' framework. The integral image [1] used by the Viola-Jones detector is then computed on these feature images respectively instead of only on the gray image. The stage classifier in Viola-Jones detector is now trained on one of these feature images. We also present a new stopping criterion for the stage training. In addition, we integrate a key points based SVM [2] predictor into the prediction phase to improve the confidence of the detection result.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"157 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125919843","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}

This work investigates the automatic detection and classification of those data type in large spoken audio archives. The corpus used for this study consists of 90 radio broadcast shows collected for preserving a large variety of Swiss French dialects. Given the variability of the language spoken in the recordings, the paper proposes a language-independent system based on structural features obtained using a speaker diarization system and various acoustic/prosodic features. Results reveal that such a system can achieve an F-measure equal to 0.85 (Precision 0.88/Recall 0.84) in retrieving folk literature in those archives. Prosodic features appear more effective and complementary to structural features. Furthermore, the paper investigates whether the same approach can be used to label speech segments into five large classes (Storytelling, Poetry, Theatre, Interviews, Functionals) showing F-measures ranging from 0.52 to 0.88. As last contribution, prosodic features for disambiguating between spoken prose and spoken poetry are investigated. In summary the study shows that simple structural and acoustic/prosodic features can be used to effectively retrieve and label folk literature in broadcast archives.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129015691","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 perform an extensive analysis of the query logs of the RAI multimedia catalogue, both at the query level and at the session level. Based on the observation that a large proportion of the queries returned zero or, conversely, too many hits, we identified three query reformulation strategies to reduce or enlarge the set of results. Our study indicates that the desire of controlling the amount of output may have a relatively limited (moderate-to-little) impact on the user's behavior, while at the same time some counter-intuitive findings suggest a suboptimal utilization of the system. The findings are useful for MDBMS developers and for trainers of professional searchers to improve the performance of interactive searches, and for researchers to conduct further work.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116000742","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}

Many researches took advantage of this notion in information retrieval. For concept-based video indexing and retrieval, this idea seems a priori valid. One of the major problems is then to provide a definition of the context and to choose the most appropriate methods for using it. Two kinds of contexts were exploited in the past to improve concepts detection: in some works, inter-concepts relations are used as semantic context, where other approaches use the temporal features of videos to improve concepts detection. Results of these works showed that the “temporal” and the “semantic” contexts can improve concept detection. In this work we use the semantic context through an ontology and exploit the efficiency of the temporal context in a “two-layers” re-ranking approach. Experiments conducted on TRECVID 2010 data show that the proposed approach always improves over initial results obtained using either MSVM or KNN classifiers or their late fusion, achieving relative gains between 9% and 33% of the MAP measure.","PeriodicalId":120769,"journal":{"name":"2012 10th International Workshop on Content-Based Multimedia Indexing (CBMI)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131999537","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 simple image signature based on the standardized moments of the wavelet coefficient distributions is proposed. This signature can be computed for each possible wavelet filter fast. An image signature map is thus obtained. We propose to use this signature map as an image characterization for Content-Based Image Retrieval (CBIR).
