I have a code for dual tree and reducing the co-efficients but i get error,please help
error is
Error using ==> cell2mat at 55
Cannot support cell arrays containing cell arrays or objects.
Error in ==> final at 9
w=cell2mat(w)
x=imread('st.tif');
x1=rgb2gray(x)
x=double(x1)
J = 3;
[Faf, Fsf] = FSfarras;
[af, sf] = dualfilt1;
w = dualtree2D(x, J, Faf, af)
threshold=0.624525
w=cell2mat(w)
NewData = w;
idx = w >= threshold;
NewData(idx) = threshold - eps(threshold);
size(I);
size(NewData);

That's because your cell array output, w, contains cell arrays within it.
Go back to your dualtree2D source code, and read the paragraph that begins,
The wavelet coefficients w are stored as a cell array.

If all the dimensions are not equal, then you will need to specify the output format you want.
If all the dimensions are equal at all levels, start at the innermost cell and cell2mat that, and having done that for all of the cells, go up one level and cell2mat _that_ and do that for all the cells at that level... then go to the level above and cell2mat again... and keep going until you end up with just a matrix.
