| 摘 要： | 由于基准日与实测图之间存在灰度变化，基于灰度不变矩的匹配方法不能满足实际匹配的要求．图像灰度变化时，对应的直方图基本形状保持不变．据此定义了基于直方围的一维不变矩，并提出基于直方图不变矩的匹配方法．由于直方图不变矩是基于一维矩的定义，运算时间大大减少．

| Abstract: | Because a grey level change exists between the reference image and the sensed image, thematching algorithm based on the grey level moment invariant will not work. A matching algorithmbased on the histogram moment invariant is presented. When there exists a grey level change, theshape of the histogram will not change. Therefore, four one-dimensional moment invariants based onthe histogram are defined and a matching algorithm based on the moment invariants of the histogramis given. As one-dimensional moments are used, the computing time is significantly saved. |
