We present a new background-subtraction technique fusing contours from thermal and visible imagery for persistent object detection in urban settings. Statistical background-subtraction in the thermal domain is used to identify the initial regions-of-interest. Color and intensity information are used within these areas to obtain the corresponding regions-of-interest in the visible domain. Within...

Segmentation is a basic operation in pattern recognition. Without a previous separation of objects in an image, shape analysis of imagery pattern cannot be carried out easily. In this paper, we will present an algorithm allowing the segmentation of contour maps into closed curves. The basic idea consists of first establishing the neighbourhood relationship of contour chains and then of finding ...

Comparative molecular field analysis and comparative molecular similarity indices analysis (CoMSIA) based on three dimensional quantitative structure-activity relationship (3D-QSAR) studies were conducted on a series (28 compounds) of indolealkanoic acid derivatives as potent diabetes mellitus inhibitors. The best prediction was obtained with a CoMFA standard model (q= 0.850, r= 0.983) and with...

For a long time, Geo-spatial information was printed on paper maps whose contents were produced once for specific purposes and scales. These maps are characterized by their portability, good graphic quality, high image resolution and good placement of their symbols and labels. These maps have been generated manually by cartographers whose work was hard and fastidious. Today, Computers are in us...

For quadratic-like maps, we show a phenomenon of sensitive dependence geometric Gibbs states: There are analytic families maps for which an arbitrarily small perturbation the parameter can have definite effect on low-temperature states. Furthermore, this is robust: open set 2-parameter that exhibit We introduce version Peierls condition contour models ensuring states concentrated near critical ...

Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) based on three dimensional quantitative structure-activity relationship (3D-QSAR) studies were conducted on a series (78 compounds) of 2, 4-diamino-5-methyl-5-deazapteridine (DMDP) derivatives as potent anticancer agents. The best prediction were obtained with a CoMFA standard model (q(2)...

Historical maps are precious materials, which show spatial distribution of land use, streets and so on at the time the maps were produced. However, the imprecision, in the geometrical sense, of the historical maps makes the task of comparison very difficult. This drawback brings us to the idea of incorporating the historical maps into GIS after rubber-sheet transformation, i.e. geometric correc...
