Hello !
So I solved my problems these ways, but I am not sure whether this is the
right ways (I seems to work).
1) This bug was due to the outputlowpass which was never allocated when
direction != 0 (direction was 1 at some time during the execution because
it was a 3D file) and m_SubsampleImageFactor = 1. Thus I moved the lines
previously in the if (direction == 0) clause
outputLowPass->SetRegions(outputImageRegion);
outputLowPass->Allocate();
outputLowPass->FillBuffer(0);
before the lines
if (m_SubsampleImageFactor > 1)
{
input = m_InternalImages[direction][idx / (1 << (direction
+ 1))];
if (direction != 0)
{
outputLowPass = m_InternalImages[direction - 1][idx /
(1 << direction)];
outputHighPass = m_InternalImages[direction - 1][idx /
(1 << direction) + 1];
}
}
2) I changed
for (unsigned int i = 0; i < m_InternalImages[direction].size(); ++i)
to
for (unsigned int i = 0; i < m_InternalImages[InputImageDimension - 2 -
direction].size(); ++i)
3) I changed
static_cast<OutputImageType*>(m_InternalImages[direction - 2][idx / (1 <<
(direction - 1))])
to
static_cast<OutputImageType*>(m_InternalImages[direction][idx / (1 <<
(direction + 1))])
Attached is the itk version of the otbWaveletFilterBank.txx with my
modifications (it works with both 2D and 3D images, in single and
multiresolution).
I have another problem with the threads, it does not seem to work if I set
more than 1 thread (on 3D output image, I have a black plane in the midle
of the z dimension but the other parts of the image are good).
Any ideas on how to solve this problem?
Thanks in advance !
Regards,
Flo
