Content-aware image retargeting is a technique that can flexibly display images with different aspect ratios and simultaneously preserve salient regions in images. Recently many image retargeting techniques have been proposed. To compare image quality by different retargeting methods fast and reliably, an objective metric simulating the human vision system (HVS) is presented in this paper. Diff...

Fixation density maps (FDM) created from eye tracking experiments are widely used in image processing applications. The FDM are assumed to be reliable ground truths of human visual attention and as such one expects high similarity between FDM created in different laboratories. So far, no studies have analysed the degree of similarity between FDM from independent laboratories and the related imp...

Nowadays industrialized countries with their high labor costs have to rely on production automation to keep their competitive advantage. One of the most flexible and powerful automation technology available today is industrial robotics. Equipped with the right tool, standardized industrial robots can perform numerous production tasks. Since acquisition and programming of an industrial robot are...

La connaissance de plus en plus précise des mécanismes physiopathologiques des hydrocéphalies a conduit aux progrès actuels dans la conception des shunts. La maîtrise des techniques chirurgicales de dérivations liquidiennes a totalement modifié leur pronostic. Cependant, qu'elle soit péritonéale ou atriale la dérivation du liquide cérébrospinal (LCS) n'est pas un geste anodin puisque plusieurs ...

Content-aware image resizing (or image retargeting) enables images to be fit to different display devices having different aspect ratios while preserving salient image content. There are many approaches to retargeting, although no “best” method has been agreed upon. Therefore, finding ways to assess the quality of image retargeting has become a prominent challenge. Traditional image quality ass...

pucker grade is one of the most important quality parameters in garments manufacturing industry. At present, seam pucker is usually evaluated by human inspectors, which is subjective, unreliable and time-consuming. Instead of subjective evaluation, this paper presents an objective method by using image analysis and pattern recognition. The evaluation system consists of image acquisition, image ...

In industrial assembly lines, seam sealing is a painting process used for making watertight seals or for preventing rusting. In the process, sealant is painted on seams located at the joints of pressed metal parts. We developed a sealing robot system that adjusts the sealing gun motion adaptively to the seam position sensed by a range sensor (a scanning laser rangefinder which senses profile ra...

An algorithm for surface domain decomposition and grid generation for overset grids is described. A complex surface domain is covered by two types of grids: seam grids and block grids. Seam grids are grids used to wrap around surface crease lines and regions of high surface curvature. Block grids are grids that cover the remaining surface regions not occupied by the seam grids. The seam and blo...

AbstractAsynchronous transfer mode (ATM) networks must de ne multicast capabilities in order to e ciently support numerous applications, such as LAN emulation, Internet protocol (IP) multicasting, video conferencing and distributed applications. Several problems and issues arise in ATM multicasting, such as signaling, routing, connection admission control, and tra c management problems. IP inte...
