Comparison of research on methods of multi-source remote sensing image fusion

This paper mainly researched on image fusion based on pixel, such as weighted fusion, principal component analysis and wavelet transform were comprehensively analyzed, that provided theoretical basis for selecting fusion methods. Evaluation standards of image fusion methods were researched at the same time, and evaluation of various on experimental results was carried out by using these standards. According to analysis of the experimental results, the characteristics of some fusion methods commonly used and scope were summarized.
