Abstract: In this paper, we propose a new interpolation technique using exponential B-spline, which is super-set of the Bspline. An interpolation kernel of exponential B-spline was proposed using IIR based technique by Unser. As another approach, this paper presents an exponential B-spline interpolation kernel using simple mathematics based on Fourier approximation. A high signal to noise ratio can be achieved because exponential B-spline parameters can be set depending on the signal characteristics. The analysis of these interpolated kernels shows they have better performance in high and low frequency components as compared to other conventional nearest neighbor, linear, spline based methods.
