A Shearlet Approach to Edge Analysis and Detection

IEEE TRANSACTIONS ON IMAGE PROCESSING, 18(5), 929–941.

By: S. Yi n, D. Labate n, G. Easley* & H. Krim n

author keywords: Curvelets; edge detection; feature extraction; shearlets; singularities; wavelets
TL;DR: This paper proposes a novel approach based on the shearlet transform: a multiscale directional transform with a greater ability to localize distributed discontinuities such as edges, which is useful to design simple and effective algorithms for the detection of corners and junctions.
