| 摘 要： | 根据图像的降质模型，基于凸集投影（POCS）原理，结合降质图像模型，提出一种使用中值滤波初值处理的高效POCS单帧图像的超分辨率重建方法。计算机仿真结果表明，和双线性内插、经典POCS方法比较，改进后的该方法重建图像信噪比平均提高2．1dB和1．1dB。

| Abstract: | In this paper,based on POCS（projection onto convent sets） principle, a high efficient single image SR algorithm is proposed by using median filter preprocessing according to imaging degradation mode. The result of computer simulation shows that the modified algorithm promote the average PSNR value 2.1 and 1.1 dB comparing with the bilinear interpolation and traditional interpolation POCS algorithm, respectively. |
