Application of PCA Numalgorithm in Remote Sensing Image Processing

Hong Dai(School of Computer and Information Engineering, Shanghai Second Polytechnic University)


A numerical algorithm of principal component analysis (PCA) is proposed and its application in remote sensing image processing is introduced:(1) Multispectral image compression; (2) Multi-spectral image noise cancellation; (3) Information fusion of multi-spectral images and spot panchromatic images. The software experiments verify and evaluate the effectiveness and accuracy of the proposed algorithm.
