A Method of the Image Edge Extraction Based on Wavelet Denoising

摘要：

When using Laplacian operator in edge extraction,the noise makes it unacceptable.To solve it.a new improvement method is proposed,which can denoise effectively and remain edge as more as possible.The experiment proves its efficiency in edge extraction.
