Epstein-Barr virus nuclear antigen 2 (EBNA2) and the Notch protein both function within the nucleus as transcriptional adaptor proteins. EBNA2 plays a key role during the immortalization of primary B-cells by Epstein-Barr virus (EBV). Notch proteins are involved in lymphomagenesis as well as in multiple cell fate decisions during tissue differentiation and(More)
In this paper, we describe our approach to the TRECVID 2008 BBC Rushes Summarization task. First, we remove junk frames and dynamically accelerate videos according to their motion activity to maximize the content per time unit. Then, we search identical sequences using a sequence alignment algorithm derived from bio-informatics and we identify and structure(More)
Visual annotation is still an open issue. The Content Based community admits that a plurality of features and systems shall be considered. We present in this paper four very different strategies using not only visual information but also text, to implement ImageCLEF2009 Photo Annotation Task. The visual features are various, such as HSV, Gabor, EDGE, SIFT,(More)
Video summarization is a useful tool which allows a user to grasp rapidly the essence of a video. In the development of this research topic we propose a new method based on different individual content segmentation and selection tools in a collaborative system. The main innovation of this work is to merge results from different approaches, so as to benefit(More)
The visibility level (VL) approach is often applied to assess the performance of vehicle lighting systems. After describing the details of the VL computational model, we review how it is ordinarily implemented for assessing night-time visibility in driving conditions. Then we present an evolution of the VL approach which consists in evaluating visible edges(More)
Signalling through the transmembrane receptor Notch is triggered by ligand binding, which induces the proteolytic cleavage of the Notch protein. This cleavage generates an intracellular fragment of the Notch protein (Notch-IC), which translocates into the nucleus and modifies transcription of target genes through its association with the RBP-J protein.(More)
In this paper we describe K-Space’s participation in TRECVid 2008 in the interactive search task. For 2008 the K-Space group performed one of the largest interactive video information retrieval experiments conducted in a laboratory setting. We had three institutions participating in a multi-site multi-system experiment. In total 36 users participated, 12(More)
During the post-production stage of film making, the film editor is faced with large amounts of unedited raw material, called rushes. Developing tools to view and organize this material is an important component of video processing. This paper describes an approach for summarizing rushes video based on the detection of repetitive sequences, using a variant(More)
