摘要
特征提取方法的选择是影响识别率的一个至关重要的因素。而印刷识别中的分类特征很多,让每一类特征具有良好的分类能力和稳定性是仍需要解决的问题。现就以具有高稳定性和抗干扰能力的八方向码特征为例,对其提取方法进行了全面的阐述。
The choice of feature extraction method is a critical factor of the recognition rate.There are a lot of classification of the printing features,how to make each type of feature has a good classification ability and stability are still issues to be discussed.Now to have high stability and antijamming capability,characteristics of the eight direction code,for example,describes the extraction methods in details.
