distribution de ce contenu visuel représente des variables linguistiques, c.-à-d. "l'occurrence est maximale" et "la distribution est maximale". L'occurrence et la distribution représentent deux ensembles flous qui nécessitent une détermination de leur fonction d'appartenance. Dans notre proposition, nous segmentons les séquences vidéo en plans (shots) comme unité de base en utilisant une trans...

Many content-based video data indexing and retrieval systems have utilized the syntactic contents of the video sequences such as color, texture, and shape. And only a few researches have addressed indexing and retrieving video data by motion. In this paper, we present a method to automatically compute motionbased indexes for video units and to retrieve video units using motion information. Sinc...

Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...

We present a set of tools that were developed for an experimental music project in which an album was created with 1,000 distinct variations and released as a digital limited edition. The tools enable the parameterisation of musical compositions created in the popular music software Ableton Live such that timelines of musical elements can be composed as keyframes and interpolated between.

This paper presents a method to control and direct a physically-based fluid simulation with user defined strokes. Strokes are interpreted as flowlines and introduce a smooth velocity field in their vicinity that allows the fluid simulation to be easily directed by an animator. We also allow the fluid to interact with arbitrarily shaped obstacles and have variable viscosity during the simulation...

This work is concerned with video indexing and retrieval based on visual features. It puts forward an approach for the automatic summary and indexing of digital videos in order to support queries based on visual content on a video database. The proposed approach was applied to a video collection containing more than 34 hours of broadcast news videos. Visual features extracted from the summarize...

Key frames and previews are two forms of a video abstract, widely used for various applications in video browsing and retrieval systems. We propose in this paper a novel method for generating these two abstract forms for an arbitrary video sequence. The underlying principle of the proposed method is the removal of the visual-content redundancy among video frames. This is done by first applying ...

This paper describes our recently developed system which captures both whiteboard content and audio signals of a meeting using a digital still camera and a microphone. Our system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the captured image sequence. It also automatically produces a set of key frames representing all the...

We present a new method for segmenting, and a new user interface for indexing and visualizing, the semantic content of extended instructional videos. Using various visual filters, key frames are first assigned a media type (board, class, computer, illustration, podium, and sheet). Key frames of media type board and sheet are then clustered based on contents via an algorithm with near-linear cos...

The Summary Description Scheme (DS) in MPEG-7 aims at providing a summary of an audio-visual program that offers the effective mechanism for efficient access to the program by abstracting the contents. In this paper, we present, in details, the Summary DS proposed to MPEG-7 that allows for efficient navigation and browsing to the contents of interest as well as overview of the overall content i...
