Glancing, Referring and Explaining in the Dialogue System Ham-rpm

The natural language dialogue system HAM-RPM converses with a human partner about scenes which either one or both are looking at directly (or have a photograph of). At present the system, which is implemented in FUZZY (LeFaivre 1977), is being tested on two domains: the interior of a living room and a traffic scene. Since it is assumed that both partners begin the dialogue with relatively littl...

Characterizing Trajectories of Moving Objects Using Natural Language Path Descriptions

The topic of this paper1 is the analysis of the semantics of the particular spatial relations 'along' and 'past' which are used to characterize the path of moving objects. The German dialogue system CITYTOUR, which answers questions about the spatial relations of objects in a scene, is presented by means of a simple dialogue example. The representational prerequisites of the static and the dyna...

Using Dialogue to Learn Math in the LeActiveMath Project

We describe a tutorial dialogue system under development that assists students in learning how to differentiate equations. The system uses deep natural language understanding and generation to both interpret students’ utterances and automatically generate a response that is both mathematically correct and adapted pedagogically and linguistically to the local dialogue context. A domain reasoner ...

Statistical Background Modeling Based on Velocity and Orientation of Moving Objects

Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...

Augmented Reality with Automatic Illumination Control Incorporating Ellipsoidal Models

| In applications of augmented reality like virtual studio TV production, multi-site video conference applications using a virtual meeting room and synthetic/natural hybrid coding according to the new ISO/MPEG-4 standard, a synthetic scene is mixed into a natural scene to generate a synthetic/natural hybrid image sequence. For realism, the illumination in both scenes should be identical. In thi...

An Intelligent System for Automatic Detection of Traffic Rules Violation From Traffic Surveillance Camera Videos

Checking traffic rule observation by vehicles play an important role in every day transportation handling either for intraor intercity travels. Also, image processing plays a great role in modern intelligent transportation system (ITS). One of the most advance ways for traffic management and rules observation studies is employing live surveillance camera videos. In this paper, a new approach to...
