Comparison of the shape of kernels. Left: heat kernel with 0.2 used as a sample data. Middle: The sample data is smoothed with heat kernel smoothing method with bandwidth σ = 9.8 making the effective bandwidth of 10. Right: iterated kernel smoothing with bandwidth σ = 0.2 and m = 49 iterations applied to the sample data.
