基于sift的图像复制粘贴篡改技术
基于sift的图像复制粘贴篡改检测算法,该算法首先提取出sift特征,用的是网上提供的提取sift的混合编程方法,然后将sift特征进行匹配,并用RANSAC算法剔除误匹配对,最后用线段将原始块和复制粘贴块中的匹配点连接起来。此算法能抵抗各种后处理操作,如旋转、尺度缩放、添加噪声等以及它们的几种组合。

目前该手写体识别系统主要分为 预处理模块: 主要包括训练数据和识别数据的读取,归一化,二值化 特征提取模块:主要包括笔划方向特征和网格密度特征,还可以根据对识别率的要求继续增加其他特征 识别(分类器)模块:主要包括SVM方法和BP神经网络的方法,其中SVM方法的识别率较高,SVM+网格密度特征, 在小字符集情况下,达到了识别率97%以上 采用OO思想编写,适合做二次开发-currently the handwriting recognition system consists of pretreatment modules : including training data and identification data read, in one, two values of feature extraction module : the main characteristics of the direction including strokes and grid density characteristics, but also based on the identification of the requirements to continue to increase other identification ( Categories) modules : include SVM methods and BP networks, which SVM method for the identification of high SVM+ mesh density characteristics, in a small set of characters to achieve a recognition rate of over 97% using OO ideological preparation, suitable for secondary development
