[Insight-users] ~vnl_svd() {} misterious runtime error

[Osc@r Math]

Again Myself


 

I´ve been debugging and find that error starts on 

 

Command

output->SetSpacing(outSpacing);

 

Function

template <typename TOutputImage>

void VTKImageImport<TOutputImage>::GenerateOutputInformation()

File

                itkVTKImageImport.txx

 

Debugging information

                outSpacing is generated like:

                                typename TOutputImage::SpacingType
outSpacing;

This is the result by traspase inSpacing data

                                outSpacing: { ????, ????, ????, { 1, 1, 2 }
};           

         {WSH?,WSH?,WSH?, { xSpacing,ySpacing,zSpacing } }.

        WSH?:=What Suppose to be here?

 

Those data passes to

if( this->m_Spacing != spacing )  HERE m_Spacing=

    {

    this->m_Spacing = spacing;

    this->ComputeIndexToPhysicalPointMatrices();

    this->Modified();

    }

Command:         this->ComputeIndexToPhysicalPointMatrices();

Function:            Void ImageBase<VImageDimension>::SetSpacing(const
SpacingType & spacing )

FILE:                      itkImageBase.txx

Var Keeps:         spacing: { ????, ????, ????, { 1, 1, 2 } };

 

 

Command:         this->Superclass::ComputeIndexToPhysicalPointMatrices();

Function:            void Image<TPixel,
VImageDimension>::ComputeIndexToPhysicalPointMatrices()

FILE:                      itkImage.txx

Var keeps:          m_Spacing: { ????, ????, ????, { 1, 1, 2 } }

 

Command:         this->m_PhysicalPointToIndex =
m_IndexToPhysicalPoint.GetInverse();

Function:            void
ImageBase<VImageDimension>::ComputeIndexToPhysicalPointMatrices()

FILE:                      itkImageBase.txx

Var keeps:          m_Spacing: { ????, ????, ????, { 1, 1, 2 } }

 

Command:         vnl_matrix<T> temp = vnl_matrix_inverse<T>( m_Matrix );

Function:            inline vnl_matrix_fixed<T,NColumns,NRows> GetInverse(
void ) const

FILE:                      itkMatrix.h

Data keeps:       m_Matrix: { { { 1, 0, 0 }, { 0, 1, 0 }, { 0, 0, 2 } } }

 

Command & Function:

operator const vnl_matrix_ref<T>() const { return vnl_matrix_ref<T>(
num_rows, num_cols, const_cast<T*>(data_block()) ); }

*data_block: E2335 Overloaded 'vnl_matrix_fixed<double, 3, 3>::data_block'
ambiguous in this context

 

Command & Function:

T const* data_block () const { return data_[0]; }

DATA:   *data_: { 1, 0, 0 }, { 0, 1, 0 }, { 0, 0, 2 }

 

And so on, but I couldn´t  find the error

Hi All
!!!

 

Recently I took back an ITK-VTK-BCB5 project, but as I know ITK & VTK
improves, I decided to update those toolkits (by the way, congrats!!! For
this big effort).

Actually, compiled ITK 3.16 & VTK 5.4.2 Releases

BCB 5 with Borland C++ compiler 5.5.

 

Today I  get a runtime error that it’s pretty mysterious (at least for me)


 

The application reads a 3D image by VTK reader, show it by VTK
renderization, send it to ITK pipeline, calculates partial derivatives &
magnitude gradient, then save Dx, Dy, Dz & |V|.

 

The image has a spacing, an origin, among others


When spacing is 1.0, 1.0, 1.0 there’s no problem, everything works fine,

but if spacing changes anyone of those dimensions, application crashes.

 

The application is capable to read image, show it, but when tries to connect
VTKReader to ITKCaster (is first action with ITK) send an “Abnormal Program
Termination”

 

In Debug mode I realize that crashes trying to execute 

~vnl_svd() {}

In vnl_svd.h file and mark an error like:


 Access violation at address XXXX 


If continue debugging, crashes too in:

~vnl_diag_matrix() {}

In vnl_diag_matrix.h file with similar error

And finally throws an “Abnormal Program Termination”


 

I didn´t know why tries to invert a matrix that contains

xSpacing     0                      0

       0      ySpacing              0

      0             0               zSpacing

 

¡¡¡ Someone could help me !!!

 

TNX in advance
