Algorithms of Image De-noising and Feature Extraction Based on Multi-scale Analysis
DAI Gui-ping
Abstract：For two typical multi-scale geometric analysis methods:Bi-dimensional empirical mode decomposition and nonsubsampled contourlet transform,four algorithm models of image de-noising and feature extraction are proposed. For each model,the algorithm principles and processes are detailedly analyzed. And then through the simulation experiments,the effectiveness and superiority of each algorithm model are verified.
