基于第二代Curvelet变换的自适应阈值去噪研究*
Research of an adaptive threshold value de-noising method based on the second Curvelet transform
摘要
Abstract
A new method for scattered point clouds by 3D scanner is presented based on the second generation Curvelet transform , which is according to the theory of the Bayes to estimate threshold and in combined with improved threshold function . The experiment shows that it can not only more thoroughly achieve noise reduction , but also restore the point clouds boundary fea-tures and details compared with the traditional threshold de-noising method .关键词
