Abstract
This paper presents a new method for nonlinear image interpolation. Previous directional interpolation methods only take the edges along a certain direction and then perform interpolation on such images. Our proposed method in its first step decomposes the image into its directional components based on fan filters presented in R.H. Bamberger (1990). These outputs differ from previous methods as it partitions the image based on its global directional features. The second step is to perform 'slope hold interpolation', a new method for image interpolation on all the directional images, and final step is to add all these directionally interpolated images to get the resultant image. Result of processing cameraman image is presented to demonstrate the effectiveness of our proposed algorithm
