Abstract

We propose a superresolution process for gray-level images based on a resolution-conversion method for discrete terrain in a space. With our resolution-conversion method, sampling a terrain and expressing it as a discrete surface allows us to estimate an original surface from a low-resolution one applying the resolution-conversion method.

灰度图像的离散几何分辨率转换
提出了一种基于空间离散地形分辨率转换方法的灰度图像超分辨率处理方法。使用我们的分辨率转换方法,对地形进行采样并将其表示为离散表面,使我们能够应用分辨率转换方法从低分辨率表面估计原始表面。
