Study of image fusion based on wavelet analysis

Image fusion is an important application of information fusion in image processing. Wavelet has become a sort of mainstream technology in the area of image fusion because it possesses favorable characteristics of localization and multiresolution at time domain and frequency domain at the same time. In this paper, the multispectral image was set as an example for the experiment. A kind of fusion algorithm based wavelet analysis and HIS transform was put forward. And the emphases of the algorithm were the selection of the wavelet bases and the processes of the algorithm. The outcome of the simulation showed that the algorithm of this paper possessed preferable fusion effect than traditional algorithm.
