Definition

Super-Resolution is an image processing technique which takes input of a single or multiple low-resolution images and produces a single or multiple high-resolution images. By Super-Resolution processing, the quality of images can be enhanced and the follow-up stage of image processing (e.g., segmentation, object recognition, object tracking, or biometric identification) can achieve a higher success rate. The goal of iris Super-Resolution is to apply Super-Resolution technique in the specific domain as in iris image in order to enhance the quality of iris image. The iris image of better quality will result in a higher verification/recognition rate in iris recognition systems.

Introduction

Image resolution is a fundamental factor for the success of all kinds of image processing techniques, ranging from  image segmentation,  object recognition, tracking, 3D shape estimation, and...
