Hi Diógenes Diógenes,
Did you run the observeWaveletDecompositionBenchmark_N_levels.m file? As stated in the readme.txt, it is the main executing reference usage file.
For a single decomposition level, set
levelOfDecomposition = 1; % level N = 1
For the inquiries regarding the variables, in image wavelet decomposition, the segments are divided according to the (H)orizontal, (V)ertical, (A)pproximate and (D)iagonal regions.
Usually, the coefficients are represented in the form (in the example of 1 level wavelet decomposition):
I hope that helps.
hi, I am a new user of Matlab, I'm trying to use the function, but is returning the error:
?? Undefined function or variable 'H'.
What H and V represent and how they should be defined?
I'm trying to make a single decomposition level grayscale images. How can I make the decomposition into multiple images at once? Thank you!
