基于NSCT的遥感图像融合性能评价及分析

In order to find out the more effective multi-resolution analysis method , a novel fusion strategy used the region-based selection operator based on non-subsampled contourlet transform is presented, and do a thorough research on the performance appraisal and computational complexity analysis of remote sensing image fusion based on non-subsampled contourlet transform, at the same time. In the experiments we compared this strategy with discrete wavelet transform (DWT) and contourlet transform (CT). The experimental results show that the computational complexity of the fusion based on non-subsampled contourlet transform (NSCT) obviously improve than DWT, but it can achieve the best fusion performance.
