提出了一种基于2DPCA和PCA的信息压缩方法,从而实现两种特征提取方法的优势互补。仿真实验结果表明,该方法不仅提取和保留了有效信息,减少了信息的存储空间,又极大地减小了计算量,有很好的特征提取性能。
This paper proposes a new information compression method based on PCA (Principal Component Analysis) and 2DP- CA,so as to realize the two complementary advantages of feature extraction method.The experimental results show that this method is not only extraction and retaining the effective information,but also reduce the information storage space,and have a good feature extraction performance.
