Joint Image GMM and Shading MAP Estimation
We consider a simple statistical model of the image, in which the image is represented as a sum of two parts: one part is explained by an i.i.d. color Gaussian mixture and the other part by a (piecewise-) smooth grayscale shadin...

Joint Image GMM and Shading MAP Estimation
mixture and the other part is a (piecewise-)smoothly varying grayscale shading function. The smoothness is ensured by a quadratic (Tikhonov) or total variation of the mixture model and the shading. Our al...

A method of piecewise-smooth numerical branching
A method of numerical branching is proposed for piecewise-smooth steady-state problems when any analytical expressionsnare not known for the regions of smoothness of the function involved. The performance of the me...

Piecewise-Linear Vector Fields
Mathematical models describing real physical systems are based on smooth and continuous functions. However, for most systems it is impossible to find even a local analytic solution. The piecewise linear approximation repres...

Vector Fields for Piecewise-Linear System
Description of real physical systems is often based on mathematical models with smooth and continuous functions. It come to reason that it is impossible to find general analytic solution. The piecewise linear approximation ...

Surfaces with piecewise linear support functions over spherical triangulations
Given a smooth surface patch we construct an approximating piecewise linear, which is based on a projective duality, we use the socalled support function representation of the surface and of the mesh, where the latter one h...

Bifurcations in piecewise-smooth steady-state problems: abstract study and application to plane contact problems with friction
The paper presents a local study of bifurcations in a class of piecewise-smooth steady-state problems for which the regions of smooth behaviour permit analytical expressions. A system of piecewise-linear equations ...

Some splines produced by smooth interpolation
The spline theory can be derived from two sources: the algebraic one (where splines are understood as piecewise smooth functions satisfying some continuity quadratic functionals with constraints). We show that the ...
