随着超高分辨率显示设备的发展，精细纹理细节的视觉感知变得越来越重要。传统的图像上采样方法要么丢失了高频纹理细节，要么时间开销很大。在本文中，我们提出了一种迭代投影重建（IPR）方法快速和有效的图像上采样。该方法通过迭代投影过程来细化高频纹理细节，并利用预先计算的投影矩阵来加速基于实例的图像重建。结果表明，该方法能够以较低的时间代价再现纹理细节。实验结果表明，该方法优于一些国家的最先进的方法。
With the development of ultra-high-resolution display devices, the visual perception of fine texture details is becoming increasingly important. Traditional image upsampling methods suffer from either loss of high-frequency texture details or very high time cost. In this paper, we propose an iterative projection reconstruction (IPR) method for fast and efficient image upsampling. The proposed method refines high-frequency texture details with an iterative projection process, and utilizes the pre-computed projection matrix to accelerate the example-based image reconstruction. As a result, the proposed method can reproduce fine texture details with low time cost. Experimental results demonstrate that the proposed method outperforms some state-of-the-art methods.
