一个进行图章识别的C＋＋类，主要采用图章图像的矩特征进行图章比对，涉及到图像特征提取与匹配。-identification seal for a C + + class, mainly stamp image features seal moment than right, relate to feature extraction and image matching.

matlabcontourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L -matlab

基于不变矩的图像识别。本程序的作用是通过训练样本，对三维图像的一帧或几帧进行特征匹配以确定图形的类别（模式识别）。-Image recognition based on moment invariants. The role of this procedure by training samples, one or several frames of the three-dimensional image feature matching to determine the category of
