Study on Fusion of Multi-spectral Remote Sensing Image and High Resolution Spatial Panchromatic Image

This paper introduces the general process and characteristics of remote sensing image fusion, studies the common algorithm of pixel-level fusion and gives four basic steps of the image fusion. The pixel-level fusion experiments of the multi-spectral remote sensing image and high resolution spatial panchromatic image are performed by the use of the four methods. More detailed information of wavelet transform-based image fusion is given. With the Brovey Transformation, the fusion of panchromatic and multi-spectral images has the best visual effect and the fastest speed.
