    Multiple sub-stories usually coexist in every episode of a TV series. We propose several variants of an approach for plot de-interlacing based on scenes clustering - with the ultimate goal of providing the end-user with tools for fast and easy overview of one episode, one season or the whole TV series. Each scene can be described in three different ways (based on color histograms, speaker diarizat... View full abstract»

    In this paper we propose a framework for automatically chaptering VoD content based on its DVD version. The idea is to benefit from artistic work performed for DVD chapter creation even if DVD and VoD video content are not exactly the same. The framework is based on a sparse to dense frame synchronization, combining both global and local image descriptions, together with adaptive video sequence sp... View full abstract»

  • Fitting Gaussian copulae for efficient visual codebooks generation

    The Bag of Words model is probably one of the most effective ways to represent images based on the aggregation of locally extracted descriptors. It uses clustering techniques to build visual dictionaries that map each image into a fixed length signature. Despite its effectiveness, one major drawback of this model is the codebook informativeness and its computational complexity. In this paper we pr... View full abstract»

    We compare the effect of different text segmentation strategies on speech based passage retrieval of video. Passage retrieval has mainly been studied to improve document retrieval and to enable question answering. In these domains best results were obtained using passages defined by the paragraph structure of the source documents or by using arbitrary overlapping passages. For the retrieval of rel...

    Politician speaker turn detection in TV Broadcast News shows is addressed in this paper. After a first role labeling pass of speaker turns among anchor, reporter and other, turns labeled as other are submitted to a politician speech detection process. The proposed approach combines acoustical and lexical cues as well as contextual information, and does not use any specific politician model (person... View full abstract»

    This paper addresses the automatic movie genre classification in the specific case of animated movies. Two types of information are used. The first one are movie synopsis. For each genre, a symbolic representation of a thematic intensity is extracted from synopsis. Addressed visually, movie content is described with symbolic representations of different mid-level color and activity features. A fus... View full abstract»

    This paper presents a new system, running on smartphone, to provide augmented reality in unconstrained context like an urban environment. Our approach is mainly based on interest points extraction and description. We use two new improvements of existing methods to increase the general performance. The first one allows optimization of the matching step with a BRIEF descriptor and a corner detector.... View full abstract»

    When considering multimedia database growth, one current challenging issue is to design accurate navigation tools. End user basic needs, such as exploration, similarity search and favorite suggestions, lead to investigate how to find semantically resembling media. One way is to build numerous continuous dissimilarity measures from low-level image features. In parallel, an other way is to build dis... View full abstract»

    In image processing, Viola-Jones object detector [1] is one of the most successful and widely used object detectors. 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... View full abstract»

    Shot detection in sports video sequences has been of great interest in the last years. 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 computat... View full abstract»

    In this paper we propose an architecture for message-privacy preserving copy detection and content identification for images based on the signs of the Discrete Cosine Transform (DCT) coefficients. The architecture allows for searching in encrypted data and places the computational burden on the server. Sign components of the low frequency DCT coefficients of an image are used to generate a dual se... View full abstract»

    This paper introduces a novel approach of video annotation by the use of context-based assistance for the annotator. The notion of context plays, actually, a significant role in the multimedia content search and retrieval systems. In fact, a semantic interpretation (or concept) separated from its context produces incomplete information. Moreover, each concept interpretation varies according to dif... View full abstract»
