图像篡改
region duplication forgery, in which a part of a digital image is copied and then pasted to another portion of the same image, is one of the simple and common image forgery techniques.
图像区域复制篡改就是将数字图像中一部分区域进行复制并粘贴到同一幅图像的另外一个区域,是一种简单而又常见的图像篡改技术。
base on this characteristic, this paper presents a passive image forgery detection algorithm which uses blind estimation of background noise.
本文利用这一特点,提出了一种基于背景噪声分析的图像真伪被动鑒别算法。
