The strategy used to develop an innovative high contrast multiterawatt femtosecond laser chain based on a hybrid (solid/gas) technology is reported. The laser system includes a Ti:sapphire oscillator generating 50 fs pulses at 950 nm, an optical para

This paper deals with image and video segmentation using active contours. The proposed variational approach is based on a criterion featuring a shape prior allowing free-form deformation. The shape prior is defined as a functional of the distance bet

In this paper, we present results of a ray tracing simulation of a stretcher-compressor arrangement for blue-green high contrast multiterawatt femtosecond laser Ti:sapphire laser chain, not only in terms of final pulse duration and contrast, but also

The problem of image segmentation through the minimization of an energy criterion involving both region and boundary functionals is considered. We study the derivation of these functionals using the notion of shape derivative. From the derivative, we
