The Combination Methods of Image Interpolation

The existing image interpolation methods have some shortcomings,i.e.,the image blur or saw-tooth shaped edges in enlarged image.In the paper,the image representation model has been modified,and the image interpolation methods are given for the plane interpolation,spherical interpolation,slope interpolation and bicubic interpolation in order to avoid the shortcomings of the traditional interpolation methods in which all the pixels are approached with the same model.Through the theoretical analysis and experimental results,the given methods of image interpolation are shown effectiveness.
