Reducing Boundary Error in Wavelet Image Compression

compression leads to large errors and artifacts at the tile and the image boundaries of thereconstructed image. To reduce boundary errors and artifacts the image is usually first with special filters near the ...

Numerical results and error estimates for the finite element solution of problems with nonlinear boundary condition on nonpolygonal domains

Problems with nonlinear boundary condition are studied on an elliptic 2nd order problem with nonlinear Newton boundary condition in a bounded two-dimensional domain. The obtained theoretical error estimates are documented o...

Distance to boundary and minimum-error discrimination

We introduce the concept of boundariness capturing the most efficient way of expressing a given element of a convex set as a probability mixture of its boundary topology) how far the given element is from the boundary. It i...

Goal-oriented error estimates including algebraic errors in discontinuous Galerkin discretizations of linear boundary value problems

We deal with a posteriori error control of discontinuous Galerkin approximations for linear boundary value problems. The computational error is estimated in the framework of the Dual Weighted Residual method (DWR) for goal-...

Verifications of primal energy identities for variational problems with obstacles

We discuss error identities for two classes of free boundary problems generated by obstacles. The identities suggest true forms of the respective error measures which measure controls (in a weak sense) approximation of free...

Analysis of the FEM and DGM for an elliptic problem with a nonlinear Newton boundary condition

in a polygon with a nonlinear Newton boundary condition, discretized by the finite element. The main attention is paid to the study of error estimates. To this end, the regularity of the weak solution is investigated and it is show...
