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.
