基于压缩传感的匹配追踪重建算法研究。给出了OMP的一种改进方案。OMP算法本身耗时过长速度过慢，本文的改 进方案将图像进行分块后再处理，从而大大降低了OMP算法每次迭代的矩阵规模。 实验结果表明，该方案在不明显降低重建效果的同时提高了运算速度。(Matching track reconstruction algorithm based on compressed sensing)

The fusion of high-spectral/low-spatial resolution multispectral and low-spectral/high-spatial resolution panchromatic satellite images is a very useful technique in various applications of remote sensing. Recently, some studies showed that a wavelet-based image fusion method provides high quality spectral content in fused images. However, most wavelet-based methods yield fused results with spatial resolution that is less than that obtained via the Brovey, IHS, and PCA fusion methods. In this paper, we introduce a new method based on a curvelet transform, which represents edges better than wavelets. Since edges play a fundamental role in image representation, one effective means to enhance spatial resolution is to enhance the edges. The curvelet-based image fusion method provides richer information in the spatial and spectral domains simultaneously. We performed Landsat ETM+ image fusion and found that the proposed method provides optimum fusion results.
