ABSTRACT
In this paper, we propose an edge detection method by using asymptotic B-spline wavelet transform. The main idea of this method is that the asymptotic B-spline wavelet transform is introduced to optimize the performance of edge detection and reduce the amount of calculation. After that, the wavelet transform based on modulo-maximum method and K-means clustering adaptive double-threshold method are used to detect the image edge. Therefore, the important edge information of image could be obtained directly, and the edge lines could be more smoother. The experiment results show that the quality of edge detection by this method is improved apparently.

A wavelet-based multiresolution edge detection and tracking
A gradient image describes the differences of neighboring pixels in the image. Extracting edges only depending on a gradient image will results in noised and broken edges. Here, we propose a two-stage edge extraction approach with contextual-filter edge ...
Optimal threshold selection algorithm in edge detection based on wavelet transform
This paper presents an optimal threshold selection algorithm, which selects the de-noising threshold according to the turbulent degree of detected edge points, in edge detection based on wavelet transform. First of all, adjacent domain division ...
An adaptive edge-preserving image denoising technique using patch-based weighted-SVD filtering in wavelet domain
Image denoising has always been one of the standard problems in image processing and computer vision. It is always recommendable for a denoising method to preserve important image features, such as edges, corners, etc., during its execution. Image ...
