摘要
为提高Hu矩对灰度的鲁棒性,从理论和实验上分析灰度乘性和加性变化对Hu矩的影响,提出一种修正的Hu矩,消除了灰度的乘性和加性影响.实验证明,该文提出的修正Hu矩能够更准确有效地对图像进行识别.
A modified Hu invariant moments was developed to improve robustness of Hu moments on gray level. The influence of gray's multiplicative and additive distortion on Hu Moments was analyzed theoretically and experimentally. Tests show that the modified Hu can recognize image more accurately.
