ROI wavelet coefficients
in [Matlab]

From: Antonis on 21 Jun 2010 05:52 Hello, I would like to ask you how to obtain the wavelet coefficients of a specific region(x:xmax,y:ymax) of the image. I would do it by cH(x/2^level: xmax/2^level, y/2^level:ymax/2^level) but as is stated in the wavelet toolbox guide "the actual lengths of the detail and approximation coefficient vectors are slightly more than half the length of the original signal." Could you please help me? Thanks! Have a nice day!
