Abstract On the basis of a summary and analysis of wavelet transformation remote sensing image fusion method, in combination with the advantages of local variance and partial differential weighted criterion, and in the light of the deficiencies of wavelet transform method in enhancing space texture information, this paper has proposed an improved wavelet transformation remote sensing image fusion algorithm. With IKONOS multi-spectral and panchromatic as fusion experiments data, the new algorithm fusion effect was comprehensively evaluated from the subjective, the objective and the object-oriented classification accuracy. The results show that the improved algorithm combined with advantages of the wavelet transform and local algorithm is quite satisfactory. It greatly remedies the defects of traditional wavelet fusion method in remote sensing image texture information loss and serves as a kind of efficient remote sensing image fusion method. With the utilization of the new image fusion method, the remote sensing image variance is raised from the original 98.28 to 164.32, the information entropy increases from 5.30 to 7.85, the average gradient rises from 1.972 to 8.807, and the image classification accuracy increases by 10.24%.
