摘　　要：基于Curvelet变换对于图像的光谱信息保留和分形原理,针对图像的纹理信息提取的特性,提出了一种基于Curvelet变换与改进的分形布朗运动分维数计算的新的融合算法。对多光谱与全光谱图像进行了融合实验,并与传统的基于小波变换和高频系数取大算法进行了对比。实验证明,文中算法在图像光谱信息保留和纹理细节信息等方面具有良好的性能。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.
