Abstract:

In this paper,an algorithm based on curvelet transform and fractal is proposed in light of the fact that the curvelet transform can keep the spectrum information and the principle of fractal can extract the texture information of the image.A fusion experiment is done using the panchromatic image and the multi spectral image,and a comparison is made with the algorithm based on the wavelet transform and high frequency coefficients.The result shows that the proposed method has a good performance on getting the spectrum and texture information.
