Shearlet approximation of functions with discontinuous derivatives | | Philipp Petersen
; | | Date: |
3 Aug 2015 | | Abstract: | We demonstrate that shearlet systems yield superior $N$-term approximation
rates compared with wavelet systems of functions whose first or higher order
derivatives are piecewise smooth away from smooth discontinuity curves. We will
also provide an improved estimate for the decay of shearlet coefficients that
intersect a discontinuity curve non-tangentially. | | Source: | arXiv, 1508.0409 | | Services: | Forum | Review | PDF | Favorites | |
