Abstract
This paper proposes an efficient image interpolation algorithm using cubic spline interpolation method. The proposed interpolation algorithm is done in two steps. In the first step, the area of the image is enlarged by inserting zeros in between every two columns and rows according to the zooming intensity as input by the user. Second step involves the estimation of correct values of those zeros so that after zooming the image does not ruptures with absurd values of the pixel. The cubic spline method is efficiently programmed in MATLAB 7.12 and results were according to the requirement
