Comparison of wave height interpolation with wavelet refined cubic spline and fractal methods

In this paper, the wavelet refined cubic spline method and fractal method are applied to improve interpolation accuracy. Results indicate that both methods show advantages over the cubic spline method, on the average, for the whole dataset. However, further analysis reveals that the methods introduced in this paper are not as effective as the cubic spline method for all gap sizes. The methods are implemented and compared at two study areas having quite different patterns of wave height.
