Chan Tony F, Shen Jianhong (Jackie): Image Processing and Analysis: Variational, PDE, Wavelet, and Stochastic Methods. [PDF]
BioMedical Engineering OnLine, 2006 Image processing is an important component of modern technologies because human depends so much on the visual information than other creatures. Image is better than any other information form for us to perceive. Among our information about the world, 99% is perceived with our eyes [1].

Conservation laws of partial differential equations: Symmetry, adjoint symmetry and nonlinear self-adjointness [PDF]
Computers and Mathematics with Applications 74 (2017) 3129-3140, 2014 Nonlinear self-adjointness method for constructing conservation laws of partial differential equations (PDEs) is further studied. We show that any adjoint symmetry of PDEs is a differential substitution of nonlinear self-adjointness and vice versa. Consequently, each symmetry of PDEs corresponds to a conservation law via a formula if the system of PDEs

Invertible Mappings of Nonlinear PDEs to Linear PDEs Through Admitted Conservation Laws [PDF]
Acta Appl. Math. 101 (2008), 21-38, 2007 An algorithmic method using conservation law multipliers is introduced that yields necessary and sufficient conditions to find invertible mappings of a given nonlinear PDE to some linear PDE and to construct such a mapping when it exists. Previous methods yielded such conditions from admitted point or contact symmetries of the nonlinear PDE.

Exotic n-d'Alembert PDE's and Stability [PDF]
arXiv, 2010 In the framework of the PDE's algebraic topology, previously introduced by A. Pr\'astaro, {\em exotic $n$-d'Alembert PDE's} are considered. These are $n$-d'Alembert PDE's, $(d'A)_n$, admitting Cauchy manifolds $N\subset (d'A)_n$ identifiable with exotic spheres, or such that $\partial N$, can be exotic spheres.

Toward Designing Intelligent PDEs for Computer Vision: An Optimal Control Approach [PDF]
arXiv, 2011 Many computer vision and image processing problems can be posed as solving partial differential equations (PDEs). However, designing PDE system usually requires high mathematical skills and good insight into the problems. In this paper, we consider designing PDEs for various problems arising in computer vision and image processing in a lazy manner ...

Symmetry and Integrability of Classical Field Equations [PDF]
Annals Nav. Acad. Gr. (Nausivios Chora) Vol. 2 (2008) 341 (in
Greek), 2008 A number of characteristics of integrable nonlinear partial differential equations (PDE's) for classical fields are reviewed, such as Backlund transformations, Lax pairs, and infinite sequences of conservation laws. An algebraic approach to the symmetry problem of PDE's is described, suitable for PDE's the solutions of which are non-scalar fields (e.g.,
