Image super-resolution method based on a hole array mask usage

Abstract

A super-resolution method based on the image registration by a photo-matrix located behind the mask with a hole array is proposed. The mask can take four different positions in relation to the photo-matrix. Each position allows the registration of one digital image using a quarter of each pixel in the matrix. Based on these images one image whose linear spatial resolution two time exceeds the resolution of each registered images is synthesized. The method is very resistant to noise and interference in the process of registration as well as to calculation errors
