A new method for image resizing

A new method for image processing, especially for image resizing, is presented. The new method produces pictures with higher precision, which is useful in 2D CT image resizing. Suppose that the given data points of an image are sampled from an original surface. The method first computes the fitting points of the original surface, then the fitting points are used to construct the interpolation surface to fit the original surface. Resizing the images by the interpolation surface makes them have higher precision and good quality. The experiments for test the efficiency of the new method shows that the resized images produced by the new method have higher precision and hence offer more detail information real application.
