Comparison of Convolutional Based Interpolation Techniques in Digital Image Processing
Póth Miklós · 2007
In this paper, we compare different types of interpolation techniques. Both sine based (linear and cubic) and spline based interpolation techniques are presented in detail. The quality of interpolation techniques are tested on doubling the size of the image in both directions. We present the accuracy of all techniques, and the frequency responses of the interpolators.
