数字图像区域复制篡改检测关键技术分析

摘要

Copy-Move forgery is a specific type of image forgery.This paper describes the model and the detecting methods of Copy-Move forgery and analyses how to select eigenvectors and detect the similar blocks.In the end, this paper advances the development way of Copy-Move forgery detecting.%本文针对数字图像盲取证技术中的区域复制篡改类型,介绍了区域复制篡改模型及检测方法,并对区域复制篡改检测技术中的特征向量选取和块匹配检测技术进行了分析,最后展望了区域篡改检测技术的发展方向.
