cqvip:In this paper we present a new image zooming algorithm based on surface fitting with edge constraint.In surface fitting,we consider not only the relationship of corresponding pixels between the original image and the enlarged image,but also the neighbor pixels in the enlarged image according to the local structure of original image.Furthermore,during surface fitting,more interpolation constraints are used in the new algorithm for improving the precision of the super sampling pixels.The experimental results show that the new method outperforms the previous methods which based on surface fitting.
