%X In order to better maintain the image of the edge information, this paper presented a Catmull-Rom enlarge image interpolation algorithm based on Canny edge detection. The detected low-resolution images of the edge with the Canny operator, and interpolated unknown point according to the similarity of source images and destination images, then modified Catmull-Rom's tangent direction and length if the interpolation point was the edge point. Experimental results show that the algorithm more clear edge than the standard traditional algorithm, it can keep the edge sharp features, reduce aliasing and improve image quality.
