Analysis of directional higher order jump discontinuities with trigonometric shearlets
Kevin Schober, Jürgen Prestin
In a recent article, we showed that trigonometric shearlets are able to detect directional step discontinuities along edges of periodic characteristic functions. In this paper, we…

Edge detection with trigonometric polynomial shearlets
Jürgen Prestin, Kevin Schober, Serhii A. Stasyuk
In this paper we show that certain trigonometric polynomial shearlets which are special cases of directional de la Vallée Poussin type wavelets are able to detect singularities alo…
