摘要
本文对于R.Y.Wong提出的用于图像匹配的不变矩法进行了分析,给出了在离散情况下平移和旋转不变性的理论证明,同时指出比例因子的不变性在离散情况下是不成立的。最后在DPS8/52计算机系统上采用四幅不同图像进行了计算机仿真实验,取得了与理论分析一致的结果。
The moment invariants algorithm based on image matching proposed by R. Y. Wong is analysed in this paper and the translation and rotation invariances of discrete moment invariants are theoretically proved. At the same time, it is pointed out that the scale invariance in discrete moment invariants is untenable. Finally, after experiments on DSP 8/52 computer system with four different images, the results which are consistent with the theoretical analysis are obtained.
