TL;DR本文通过引入 Local Texture Estimator (LTE) 的方法，使 implicit function 可以在连续的过程中捕捉细节，在 2D Fourier 空间表征图像纹理，达到了显著的图像超分辨率重建性能，并且在运行时间上比以往的方法更高效。
Abstract
Recent works with an implicit neural function shed light on representing images in arbitrary resolution. However, a standalone multi-layer perceptron (MLP) shows limited performance in learning high-frequency com
