摘要
为了提高重构的图像质量,给出了模拟-修正迭代的凸集投影(POCS)超分辨率图像重构方法和具体实现步骤。针对重构的超分辨率图像高频分量不足的缺点,提出了一种有效的改进方法。该方法通过对点扩散函数(PSF)的改进做到了有效地保留POCS超分辨率图像重构算法中的边沿信息。仿真实验结果表明,该方法可行性好,能够有效地保持高频分量,从而达到提高图像质量的目的。
For the purpose to improve image reconstruction quality, a POCS-based simulation-correction iteration method to reconstruct super-resolution images is described in this paper. A novel method is designed for overcoming the lack of high- frequency component in reconstructed images. The edge information in POCS super-resolution image reconstruction algorithm is kept effectively through the improved PSF. Experimental results show that the proposed algorithm has good feasibility, and can impove the image quality by retaining high frequency component.
