Multilevel Edge Detection Based on B-spline Dyadic Wavelet
摘要
Abstract
This paper proposes a wavelet based multilevel edge detection method that exploites spline dyadic wavelets and a frame work similar that of Canny’s edge detector.Using the recently proposed dyadic lifting schemes by Turghunjan et al, spline dyadic wavelet filters have been constructed, which are characterized by higher order of regularity and have the potential of better inherent noise filtering and detection results. Edges are determined as the local maxima in the sub-bands at different scales of the dyadic wavelet transform. Comparison reveals that our meth⁃od performs better than Mallat’ s and Canny’ edge detector.关键词
