An Image Interpolation Algorithm Based on Edge Gradient
Duan Jian-hui · Jisuanji gongcheng · 2013
Aiming at the problem of blur boundaries and low computational efficiency in traditional image interpolation algorithms,an image interpolation algorithm based on edge gradient is proposed.It uses Roberts edge detection operator to determine the color segmentation and interval boundary threshold,makes use of three space points to constructed plane,and gives the interpolation formula.Experimental results show that,this algorithm can protect the image details,improves image scaling quality and operation efficiency.
