applies wavelet filters to an image
ImageList = CreateWaveletFrames(Image, WaveletType, MaxLevel);
2D matrix of type uint8, uint16, uint32 or double
constant of type uint8, the following values are possible:
WAVELET_DAUBECHIES_X, 2 <= X <= 20, X = 2 k, k is a positive integer
WAVLET_COIFLET_Y, 6 <= Y <= 30, Y = 6 k, k is a positive integer
WAVELET_CDF
integer greater than zero
3D matrix that contains horizontal, diagonal and vertical details (in this sequence) for each level. ImageList(:, :, $) contains the approximation at MaxLevel.
This function applies wavelet filters to an image. Unlike the discrete wavelet transform, the image is not down sampled at any level, but the filters are dilated [1].
