摘要
在分析POCS算法的基础上,提出一种基于残差高频提升的POCS高分辨图像生成方法。实验表明,与传统的双线性插值、三次插值方法相比,其生成图像的PSNR有明显提高,与有限凸集连续投影方法相比,也有一定程度的提高。图像细节部分的主观效果得到较大改善。
A improved Projection Onto Convex Set algorithm for high-resolution image reconstruction based on the residual high frequency boost is proposed after the POCS algorithm idea is analyzed in this paper. The experiments show that this algorithm compared to the bi-linear and cubic splines image interpolation method and convex restriction set projection method, the PSNR of reconstruction image is obviously raised and subjective effect of image detail is improved.
