Method Detail

transform

public void transform(float[] s)

Does an in-place Haar wavelet transform. The length of data needs to be a power of two. It is based on the algorithm found in "Wavelets Made Easy" by Yves Nivergelt, page 24.

Parameters:

s - The data to transform.

inverseTransform

public void inverseTransform(float[] data)

Does an in-place inverse Haar Wavelet Transform. The data needs to be a power of two. It is based on the algorithm found in "Wavelets Made Easy" by Yves Nivergelt, page 29.

Parameters:

data - The data to transform.
