Abstract

In this paper we illustrate a novel image interpolation method based on the amalgamation of bicubic interpolation and 2D interpolation filter. First, bicubic interpolation algorithm is applied interpolating pixels to create a high resolution image. Then 2D interpolation filter algorithm is applied along columns and rows modifying the interpolated values to produce super resolution image. The second algorithm preserves edge smoothness and refines the interpolated pixels to produce visually high quality images. The results demonstrate that our new interpolation algorithm significantly enhances the quality and Peak Signal to Noise Ratio (PSNR) of the interpolated images over ICBI and iNEDI interpolation methods.
