Nonlinear Diiusion Scale-spaces: from the Continuous to the Discrete Setting
نویسنده
چکیده
A survey on continuous, semidiscrete and discrete well-posedness and scale-space results for a class of nonlinear diiusion lters is presented. This class does not require any monotony assumption (comparison principle) and, thus, allows image restoration as well. The theoretical results include existence , uniqueness, continuous dependence on the initial image, maximum-minimum principles, average grey level invariance, smoothing Lyapunov functionals, and convergence to a constant steady state.

DISCRETE AND CONTINUOUS SIZING OPTIMIZATION OF LARGE-SCALE TRUSS STRUCTURES USING DE-MEDT ALGORITHM
Design optimization of structures with discrete and continuous search spaces is a complex optimization problem with lots of local optima. Metaheuristic optimization algorithms, due to not requiring gradient information of the objective function, are efficient tools for solving these problems at a reasonable computational time. In this paper, the Doppler Effect-Mean Euclidian Distance Threshold ...
متن کاملScale-space Properties of Nonlinear Diiusion Filtering with a Diiusion Tensor
In spite of its lack of theoretical justiication, nonlinear diiusion ltering has become a powerful image enhancement tool in recent years. The goal of the present paper is to provide a mathematical foundation for continuous nonlinear diiusion ltering as a scale-space transformation which is exible enough to simplify images without loosing the capability of enhancing edges. By studying the Lyapu...
متن کاملExponential stability for nonlinear ltering
We study the a.s. exponential stability of the optimal lter w.r.t. its initial conditions. A bound is provided on the exponential rate (equivalently, on the memory length of the lter) for a general setting both in discrete and in continuous time, in terms of Birkhoo's contraction coeecient. Criteria for exponential stability and explicit bounds on the rate are given in the speciic cases of a di...
متن کاملConservative image transformations with restoration and scale-space properties
Many image processing applications require to solve problems such as denoising with edge enhancement, preprocessing for segmentation, or the completion of interrupted lines. This may be accomplished by applying a suitable nonlinear anisotropic diiusion process to the image. Its diiusion tensor is adapted to the differential structure of the underlying image. Although being image enhancement too...
متن کاملFORCED WATER MAIN DESIGN MIXED ANT COLONY OPTIMIZATION
Most real world engineering design problems, such as cross-country water mains, include combinations of continuous, discrete, and binary value decision variables. Very often, the binary decision variables associate with the presence and/or absence of some nominated alternatives or project’s components. This study extends an existing continuous Ant Colony Optimization (ACO) algorithm to simultan...
