| Abstract: | The nearest neighbor interpolation,the bilinear interpolation,and the bicubic interpolation,all are commonly used interpolation algorithms,with the add of Matlab,the paper realizes the three interpolations.It shows in experiment that,there are better continuity and high simulation for topography. |
