基于帧选择和多帧降质图像盲解卷积的自适应光学图像恢复

自适应光学系统受观测条件与自身条件的限制,通常只能对受大气湍流影响的降质图像进行部分校正.提出一种基于帧选择与多帧降质图像盲解卷积的事后处理方法进行自适应光学图像高分辨力恢复.该方法通过帧选择技术筛选出合适的多帧降质图像参与迭代盲解卷积运算,不需要除正性限制外的任何先验知识,并已应用于云南天文台1.2m望远镜61单元自适应光学系统所观测到的星体目标图像恢复中.实验结果表明:该方法可以有效补偿自适应光学系统校正残差对图像的影响,恢复出达到衍射极限的图像.

Adaptive Optics Images Restoration Based on Frame Selection and Multi-frame Blind Deconvolution

The adaptive optics can only partially compensate the image blurred by atmo- spheric turbulent due to the observing condition and hardware restriction.A post-processing method based on frame selection and multi-frame blind deconvolution to improve images partially corrected by adaptive optics is proposed.The appropriate frames which are picked out by frame selection technique is deconvolved.There is no priori knowledge except the positive constraint.The method has been applied in the image restoration of ce...
