中文摘要:低分辨率图像的SNR、图像之间的配准误差对超分辨率重构效果的影响是该技术在遥感领域应用的瓶颈。本文针对图像SNR对超分辨率重构的影响,根据IBP算法理论,改进IBP算法,实验表明改进的算法收敛速度快,相对于传统的POCS与IBP对低SNR的低分辨率图像重构有更好效果。 |

Abstract:the SNR of low-resolution images and the registration error among them are bottle-neck to the application of Super-reconstruction in remote sensing domain. This paper improves the IBP algorithm to reduce the affect of SNR to reconstruct. Experiment indicates that the improved algorithm has faster convergence speed and better effect to the traditional POCS and IBP algorithm. |
