An efficient method based on wavelet for fusion of multi-sensor satellite images

In this paper an efficient fusion algorithm for remotely sensed images has proposed. The wavelet tool is used for the decomposition of the images at different resolutions. By applying the fusion rules at different components (Approximated and Detailed) the desired output was obtained. The results of the proposed fusion algorithm are compared with the conventional Principal Component Analysis method. It is proved by the quantitative analysis, the proposed one outperforms the existing conventional fusion technique.
