This paper describes CASIT model (CAlculation of SImilarity of Text). Starting from a coarse confrontation of text documents, based on the Latent Semantic Indexing model (LSI), CASIT method calculates in a finer way, the rate of similarity between model documents of text and others which are confronted to them. Our approach takes into account the… (More)
—This work is in the field of video surveillance including motion detection. The video surveillance is one of essential techniques for automatic video analysis to extract crucial information or relevant scenes in video surveillance systems. The aim of our work is to propose solutions for the automatic detection of moving objects in real time with a… (More)
This paper propose a based CASIT  audio retrieval model. CASIT method is developed for our text information retrieval system witch gives good results. We have extended the CASIT method to the video and audio applications. In this paper we present its application in the audio content-based retrieval. The adapted method is called CASIA (in French: CAlcul… (More)
This paper presents a new method of video sequence segmentation. The principal aim of our approach is the detection of cuts suites in a video sequence (boundaries of transactions). The method is based on two thresholds which allow the localization of transactions suites in a video sequence.
