Abstract

We present a new digital image interpolation technique and analyze its use in digital photography. Our main goal is generate interpolated images with high quality, eliminating or drastically reducing distortions caused by reconstruction error. Our initial hypothesis is that interpolation techniques with frequency response closer to ideal reconstruction can reduce or eliminate reconstruction error, improving image quality. The proposed technique is a new 2D third-order filter, implementing discrete convolution between image samples and interpolation coefficients that are different for each interpolated pixel. To validate the proposed technique, we compared it with piecewise constant, linear and cubic interpolators.
