CAOS is an implementation model for object oriented user interfaces. It extends the well-known PAC model with more detailed knowledge of the application, resulting in less effort to implement dialogues, and more power in the underlying support system. This in turn results in cheaper user interfaces with higher quality, and increased consistency.

Shape similarity estimation of objects is a key component in many computer vision systems. In order to compare two shapes, salient features of a query and target shape are selected and compared with each other, based on a predefined similarity measure. The challenge is to find a meaningful similarity measure that captures most of the original shape properties. One well performing approach calle...

Current prototype-based languages suffer from an inherent conflict between inheritance and encapsulation. Whereas encapsulation tries to hide implementation details from the user, inheritance depends at least to some extent on exposing these implementation details. We propose a powerful calculus with dynamic object modification which does not have this conflict. This calculus constitutes a form...

Users interact with a database system through a set of database languages and this makes designing database languages a very challenging task to a computer software engineer. A set of welldefined database languages must be easy to learn, easy to understand and powerful enough to capture semantic of a problem domain. This paper discusses design issues of a proposed database language, namely Exte...

ESQL : an extended SQL with object and deductive capabilities. HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée a...

Today, most multimedia (MM) applications store their data objects in a proprietary way, usually in files on some storage device in some format that is tailored exactly to the necessities of this one application. But MM data objects (MMOs) are expected to exist for long periods of time and to be accessed by many different applications. Additionally, the employment of new opportunities offered by...

In many tracking applications, the extent of the target object is neglected and it is assumed that the received measurements stem from a point source. However, modern sensors are able to supply several measurements from different scattering centers on the target object due to their high-resolution capability. As a consequence, it becomes necessary to incorporate the target extent into the estim...

This paper presents a novel deductive object base language, called ROL (Rule-based Object Language), which has been implemented at the University of Regina and is available via anonymous ftp. It eeectively integrates important features of object-oriented databases and deductive databases into a uniform framework. It supports object-oriented features such as object identity , complex objects, cl...

In this paper we consider the problem of extended object tracking. An extended object is modelled as a set of point features in a target reference frame. The dynamics of the extended object are formulated in terms of the translation and rotation of the target reference frame relative to a fixed reference frame. This leads to realistic, yet simple, models for the object motion. We assume that th...
