With the development of the remote sensing, multi-sources images with the same area are more and more rich, we could gain more accurate and richer information from the fused image than from the single image.This paper tests the fusion of multi spectral bands and panchromatic band of SPOT5 image based on the multi scale analysis in the pixel-based fusion level.The main methods are wavelet transformation and curvelet transformation.Both methods can divide the original image into low frequency parts and high f...
