形状特征的七个不变矩，用matlab实现,Shape characteristics of the seven moment invariants, using matlab to achieve

Recovering 3-D structure from motion in noisy 2-D images is a problem addressed by many vision system researchers. By consistently tracking feature points of interest across multiple images using a methodology first described by Lucas-Kanade, a 3-D s

图象 处 理和模式识别中经常根据物体的形状来识别物 体或对物体进行分类。形状特征可以分为区域特征和边界特 征两大类，矩不变量是最基本的形状特征。Hu提出的矩不变 量是图象区域内部细节的描述，是一种区域特征。它是建立 在对一个区域内部灰度值的统计分析基础上的，需要目标区 域的所有象素参与运算-Image processing and pattern recognition are often based on the shape of objects to identify o
