Abstract

The paper presents a new fast interpolation method based on edge extraction. Our method extracts image edge by improved canny operator which has two specified thresholds first. Then for different areas, it chooses different methods. It can keep edge details while doing quick interpolation. The experimental results show that the effect of this method can hold the edge details very well, and it is obviously superior to the traditional ways. The method provides a better initial image for the super resolution reconstruction.
