| 摘 要： | 由于成像系统内部和外部的因素，使得获取的图像产生退化。为获取高分辨率图像，图像超分辨技术获得迅速发展。基于各向异性正则化提出了一种盲Poisson MAP算法，该算法同时估计高分辨图像和包含了位移因素的模糊函数，与基本的盲Poisson MAP算法相比，有效地抑制了振铃效应，清晰度有很大改善，峰值信噪比大约提高7 dB。

| Abstract: | The image obtained by some sensors will be degraded unavoidably due to some inner and outer reasons of imaging system.In order to obtain high resolution image,the image super-resolution technology has been developed rapidly.A novel blind Poisson MAP algorithm is established,which may synchronously estimate high-resolution image and blur function containing shift factors.Compared with fundamental blind Poisson MAP algorithm,this algorithm can suppress oscillatory artifacts effectively and improve the definition greatly and increase peak SNR about 7 dB. |
