Abstract :
Image magnification is an important topic in the field of digital image processing. The realization of a varty of interpolation algorithm is now a hotspot for research. The paper first useing the interpolation algorithm of cubic spline curve to realize image magnification, then using interpolation algorithm of cubic convolution for image edge serrated on post-processing, thus make objective image with higher resolution and good smoothness. On the image edge, the serrated phenomenon is solved and a good visual effect is achieved.
