public final class FastDaubechies2
extends FWT
This is a very fast implementation of the Fast Wavelet Transform. It uses in-place computations for less memory usage. Data length should be a power of 2 a be at least of length 4. Handles boundaries by assuming periodicity. Ideal for image processing or processing large amount of data. Uses floats for more performance. Safety is minimal, so be careful!
