Algorithm of Image Rotation Based on New Interpolation Method

Rotation algorithm for image interpolation methods has some shortcoming.It often can make the image blur or have saw-tooth shaped edges phenomenon.This paper changed the model of expressing image.A image interpolation method combining plane interpolation and spherical interpolation was proposed.It avoids the traditional interpolation uses unified model to approximate all pixels.In different circumstances it will use different interpolation methods.Finally,the theoretical analysis and experimental results show the effectiveness of the method.
