Image interpolation method is used to process the image where increase in size of the given image is done by a scaling factor. The method of image interpolation is used in medical imaging field, digital photographic filed, film scanning media etc. Attaining reversibility is an important need in data hiding field which is attained using the image interpolation technique. Image interpolation is also used in the reconstruction of Computer Tomography (CT) images and Magnetic Resonance Images (MRI). The need of image interpolation is low processing speed and good visual quality.
