Edge detection of high resolution remote sensing imagery using wavelet

In this paper, the 3-level B-spline wavelet transform is applied to extract different types of edges, according to the singularity exponent of edges from high resolution remote sensing imagery. The gradient algorithm, Laplacian algorithm, and Robert algorithm are classic linear algorithms. However t...
