Histogram Modication via Partial Dierential Equations

چکیده
The explicit use of partial di erential equations (PDE's) in image processing became a major topic of study in the last years. In this work we present an algorithm for histogram modi cation via PDE's. We show that the histogram can be modi ed to achieve any given distribution. The modi cation can be performed while simultaneously reducing noise. This avoids the noise sharpening e ect in classical algorithms. The approach is extended to local contrast enhancement as well. A variational interpretation of the ow is presented and theoretical results on the existence of solutions are given.

A High Order Finite Dierence Method for Random Parabolic Partial Dierential Equations
In this paper, for the numerical approximation of random partial differential equations (RPDEs) of parabolic type, an explicit higher order finite difference scheme is constructed. In continuation the main properties of deterministic difference schemes, i.e. consistency, stability and convergency are developed for the random cases. It is shown that the proposed random difference scheme has thes...

متن کاملApplying AXIOM to Partial Di erential Equations
We present an AXIOM environment called JET for geometric computations with partial dierential equations within the framework of the jet bundle formalism. This comprises especially the completion of a given dierential equation to an involutive one according to the Cartan-Kuranishi Theorem and the setting up of the determining system for the generators of classical and non-classical Lie symmetrie...
