Restoration of Hyperspectral Remote Sensing Image Based on MTF

摘要

Due to the effect of atmosphere, optics, detector and satellite motion etc, remote sensing images were often degenerated. Image restoration technology can improve image quality and interpretation capability. This paper summarized how to use edge method to measure the MTF of hyperspectral remote sensing image step by step, including the theory of edge method and the measure. It introduced the way of wiener filter and analyzed the mean, variance, entropy, average gradient, edge energy. Experimental results indicate that the quality of the image restoration based on MTF has obviously improved, and achieved good restoration results.
