In this report, we propose a wavelet-based content descriptor with which we implement an image retrieval system. Initially, we propose the wavelet-based weighted standard deviation texture descriptor. We then show how to extend this descriptor to characterize both texture and color in images. Thus, we obtain a compact feature vector that characterizes images in terms of both texture and color. ...

The paper is concerned with robust H∞ non-fragile controller design for uncertain descriptor systems with time-delay. A descriptor system has potential to describe a wide class of physical systems. It can give a representation of the system with algebraic constraints. A unique characteristic of descriptor systems is possible impulse modes and nonregularity, which do not appear in state-space sy...

This paper presents a dominant color descriptor technique for medical image retrieval. The medical image system will collect and store into medical database. The purpose of dominant color descriptor (DCD) technique is to retrieve medical image and to display similar image using queried image. First, this technique will search and retrieve medical image based on keyword entered by user. After im...

This study explores ways to increase both the usability and accuracy of design information retrieval and reuse. The DedalAI system attempts to achieve these goals by automatically indexing design concepts in electronic notebooks. DedalAI relies on a two part query structure: a descriptor, which is a generic design concept, and a subject, which is a specific part of a design model. DedalAI build...

The most important part of an Augmented Reality system is the tracking system to support an accurate and robust registration. In outdoor environments, the continuously changing environmental characteristics and elements make hard to achieve this tracking process. The main point of this operation is that the descriptor has to work with great accuracy in all kind of situations. The most used desc...

We describe a recently developed Descriptor Systems Toolbox implemented under Matlab. This Toolbox relies on the object oriented approach for control systems analysis and design provided within the standard Control Toolbox of Matlab. The basic approach to develop the Descriptor Systems Toolbox was to exploit the powerful matrix and system object manipulation features of Matlab via flexible and ...
