Title Implemention of Nonlocal Pansharening Image Fusion
Abstract
Fusion of multi modal of the remote sensing image is an important problem in remote sensing image processing and subsequent recognition. With the fusion of multi spectral images, the panchromatic image and low spatial resolution and high spatial resolution of the multi spectral image,we can get high spatial resolution,and this method calls Pansharpening technology what is an important method for remote sensing image fusion. I have studied and compared 5 Pansharpening fusion algorithm.
This paper reviews the research status of Pansharpening algorithm, around 5 Pansharpening algorithm research, algorithm design, program implementation and experimental analysis. The concrete content is:
(1) The fusion algorithm based on HIS, Brovey fusion algorithm, and the image fusion algorithm based on principal component analysis and producttransformation, the design of the application, and compared the effect of image fusion.
（2） This paper studied the non Pansharpening model design of local, non localPansharpening fusion algorithm.
（3） Taking visual c++ as the development language, combined with the MFC framework, implementation of the prototype design of image fusion.
Experimental results show: the non local Pansharpening algorithm compared with other image fusion algorithm has certain advantages and adaptability.
Keywords: remote sensing image fusion, Pansharpening algorithm, multi spectral image and panchromatic image,
