摘要
从遥感影像数据出发,对基于小波变换方法的融合模型、小波变换的算法实现及其改进方法,以及小波变换的特点和客观评价标准等方面,进行了比较全面的论述。对小波变换在遥感影像融合中需进一步研究的问题进行了探讨,指出应用多进制小波进行融合是其主要的发展趋势之一。
The fusion model based on the wavelet transform (WT) method, typical realization approaches and improvements of the method as well as WT method's characteristics and objective evaluation criteria are discussed comprehensively in terms of remote sensing images. Finally, some issues concerning the WT method in remote sensing image fusion are studied, and it is pointed out that the application of multi-band wavelet transform fusion method is a major trend.
