Abstract: The traditional fusion algorithms of transform domain image can’t clearly describe the edge of contour and the directional texture, and the linear nonstationary signal is usually unable to obtain a good result. In view of the above problems, this paper presents an image fusion algorithm that combines Contourlet transform and image regional features. This algorithm, based on the feature of high-frequency region and low-frequency region in Contourlet space, applies the method of energy feature matching in low-frequency region and fractal feature matching in high-frequency region to fuse. The experiments show that this algorithm performance is better than the traditional Contourlet fusion and wavelet fusion.
