What is presented in this paper is our work in the area of image organization and retrieval in Image Databases using global color features and spatial color distribution of images. We suggest extending the use of image histograms to characterize the global and local color properties of an image and to preserve its intrinsic geometric information. We have(More)
In this paper, we describe a system for image databases organization and retrieval based on the pictorial content representation. We suggest extending the use of image histograms to characterize the global and local color properties of an image and examine the effect of the degree of image segmentation and a number of known color reduction algorithms on the(More)
Abstract One of the basic problems in the creating of the Realistic Image Databases (RIDB) structure is the efficient organization of the image retrieval. As a result of the analyses of the retrieval strategies we made, incl. GIS realistic images, we can make the conclusion that the solution of the problem for effective image retrieval is the approach for(More)
The goals of the modern Computer-assisted Instruction systems are ultimately achievable only through the application of artificial intelligence techniques to the implementation of teaching strategies. The author of the traditional Computer-assisted Instruction course must explicitly predict and program all possible paths through the lessons, including(More)
Mobile users connected to the WiMAX<lb>technology can use five different service classes<lb>according to their different needs. In this paper we<lb>propose priority based uplink scheduling scheme for<lb>IEEE 802.16 standard that improves the QoS<lb>performances of the WiMAX service classes, especially<lb>when the number of connections gets higher.(More)
