error LNK 2019
Hello, I am trying to run the code wavelet2d.cpp but I am getting the following
error:
wavelet2d.obj : error LNK2019: unresolved external symbol _fftw_destroy_plan
referenced in function "double __cdecl convfft(class std::vector<double,class
std::allocator<double> > &,class std::vector<double,class
std::allocator<double> > &,class std::vector<double,class
std::allocator<double> > &)"
(?convfft@@YANAAV?$vector@NV?$allocator@N@std@@@std@@00@Z)
I am using Microsoft Visual Studio 2010 and OpenCV 2.4.3.
I linked the wavelet2d.lib in the additional dependencies.
I also placed the dll files in the opencv folder.
Can you please help me?

This appears to be a linker error. Make sure that the two DLLs (libfftw3-3.dll
and wavelet2d.dll ) are placed in the Project "Debug" folder next to your exe
file. Also check that the correct header file ( wavelet2d.h) is included .

Hello again. I need only one image for the wavelet transform.
I am doing a project on hand vein and I need to extract the features by
applying wavelet transform and for this I need only one wavelet transform image
but not several images decomposed totally in one window.
Do you know how I can do it?

It is straightforward. dwt_output vector contains all the images stored
sequentially in a one dimensional vector.
dwt output vector (dwt_output) is a 1D vector and the rows and
columns of A,H,V,D are stored in length vector. length(0) and
length(1) store the rows and column values at level J, length(2) and
length(3) store the rows and column values at level J-1 etc.
So A(j) part is the first length(0)*length(1) values stored in
dwt_output vector followed by H(j),V(j) and D(j). All A,H,V and D at
the same level are of same dimensions so if length(0)=15 and
length(1)=20, you can extract first 300 values as A(j), next 300 as
H(j) and so on. More here.

Also check the idwt_2d_sym and idwt_2d codes at
http://code.google.com/p/wavelet1d/source/browse/trunk/wavelet2d/src_MINGWDLL/wa
velet2d.cpp
eg. lines 726-746

Could you elaborate more about below statement? How can I generate the
fftw3.lib?
I appreciate your help.
In order to link to them from Visual C++, you will need to create .lib "import libraries" using the lib.exe program included with VC++. Run:
lib /def:libfftw3-3.def
lib /def:libfftw3f-3.def
lib /def:libfftw3l-3.def

I solved my problem with this link:

I hope it could be helpful for the others.
Cheers
