针对现有融合方法存在的光谱信息和空间细节信息不能较好兼顾的问题，提出了一种遥感图像小波融合算法。根据高分辨率遥感图像自身的空间尺度，采用多进小波分析技术较好地解决了不同尺度遥感图像空间细节的表达问题，同时利用基于方向能量统计量的自适应融合准则较好地解决了融合中的光谱信息保留问题。实验结果表明，该融合方法在保持全色图像的高空间分辨率的同时，提高了融合图像的光谱保持度。

Aiming at a worse tradeoff between spectrum information and spatial details of present fusion methods, a new algorithm is proposed to process the remote sensing data fusion. The algorithm adopts a multi-band wavelet transform to analyze the image, at the same time, it uses directional energy statistics to evaluate the spatial texture and edge. It can solve the balance between the texture enhancement and spectrum preservation. Experimental results show that this algorithm can improve the spatial resolution, and enhance the spectrum preservation.
