Edge enhancement by local deconvolution
In this paper a new approach for blurred image restoration is presented. Our algorithm is based on human vision which zooms back and forth in the image in order to identify global structures or details. Deconvolution parameters are estimated by an edge detection and correspond to the ones of a chosen edge detection model. The segmentation is obtained by merging multiscale information provided b...
متن کاملImage Enhancement by Edge-preserving Filtering
Image enhancement is useful when the details in an image are lost due to various reasons. I t is common to subtract a mask from a given image to enhance the details. The trick is how to obtain a good mask. We describe here how an edge-preserving filter can be used to generate a mask which is smooth over areas with fine details, yet preserving most of the edges. Experiments with real images show...
متن کاملLocal Evolutionary Search Enhancement by Random Memorizing
| For the calibration of laser induced plasma spectrometers robust and eecient local search methods are required. Therefore, several local optimizers from nonlinear optimization, random search and evolutionary computation are compared. It is shown that evolutionary algorithms are superior with respect to reliability and eeciency. To enhance the local search of an evolutionary algorithm a new me...

متن کاملOptimal Mixing Enhancement by Local Perturbation
We consider the problem of how to apply local perturbations to optimally enhance the mixing of a (possibly time-dependent) dynamical system. We develop a flexible modelling approach based on the transfer operator of the dynamical system, and pose the problem in the language of convex optimisation. The optimal local perturbations can then be efficiently computed, at discrete time instants, by st...
