Agree with gokhan :(

Thanks Gokhan & Ahmed.

RESAMPC is a Mex file in the Contourlet toolbox. It is written by Minh N. Do. I have problem in fixing the errors generated by the function in Matlab as follows:

Error in ==> resamp at 44

y = resampc(x, type, shift, extmod);

Error in ==> qpdec at 32

y = resamp(x, 2);

Error in ==> fbdec_l at 41

[p0, p1] = qpdec(x, type2);

Error in ==> dfbdec_l at 38

[x0, x1] = fbdec_l(x, f, 'q', '1r', 'qper_col');

Error in ==> pdfbdec at 50

xhi_dir = dfbdec_l(xhi, dfilt, nlevs(end));

Error in ==> denoisedemo at 40

y = pdfbdec(nim, pfilt, dfilt, nlevs);

I used Windows OS. I need help please.

In my opinion there is a problem with the image lena.png, not with software. I suppose that you use RGB image instead of gray scale. Try to replace in source code lena.png with barbara.png (this image is provided with this toolbox) or use image lena.png from the attachment.

mm, I dont have problems to run that demo.

What windows do you have 64 or 32 bits?

May be you need to recompile

try mex resamp.c

if you get errors you can try first

mex –setup

I thank all the contributors. I have discovered the problem I encountered. It was an issue of Matlab supported compilers. I visited http://www.mathworks.com/support/compilers/R2013a/index.htm and l have installed an appropriate C++. Also, I tried the suggestion made by Jose. So I can now run the Demo in the toolbox.

hi Abdulazeez Ajao,

I can't open the link. can you help me to solve the problem of contourlet toolbox ?

Those are errors i obtain:

Undefined function 'resampc' for input arguments of type

'double'.

Error in resamp (line 44)

y = resampc(x, type, shift, extmod);

Error in qpdec (line 32)

y = resamp(x, 2);

Error in fbdec_l (line 41)

[p0, p1] = qpdec(x, type2);

Error in dfbdec_l (line 38)

[x0, x1] = fbdec_l(x, f, 'q', '1r', 'qper_col');

Error in pdfbdec (line 50)

xhi_dir = dfbdec_l(xhi, dfilt,

nlevs(end));

Error in decdemo (line 68)

coeffs = pdfbdec( double(im), pfilter, dfilter, nlevels

);

Did you got the same errors ?

Hello Ribose,

I guess the challenge you are having is with the resampc.c file. (1) install a compatible C or C++ compiler on your system (2) run from Matlab >mex –setup to see if the compiler is successfully configured (3) recompile the file >mex resampc.c (4) test the code with the image provided by Grzegorz Knor.

It works thank you :)

I had the same problem running a 32bit mex file on my 64bit windows.

hi Abdulazeez Ajao,

do u khow whats compatible C or C++ compiler  for matlab2014a??
