[Insight-users] reusing Filters

[marquis2 at etu.unige.ch]

hi,

is it ok to reuse a filter many times or does it have to be instanciated once
per use ? the docs suggests the first but I have a SIGABRT with a
BinnaryThresholdImageFilter< ImageType, ImageType >
(with ImageType = short, 2) for every _second_ image I want to filter:

Program received signal SIGABRT, Aborted.

code is:

thresholdFilter->SetInput(image);
thresholdFilter->SetLowerThreshold( threshold );
thresholdFilter->SetUpperThreshold( itk::NumericTraits< PixelType >::max());
thresholdFilter->SetOutsideValue( 0 ) ;
thresholdFilter->SetInsideValue( white );
thresholdFilter->Update();

is there other "cleaning"
I should make between each use so that it does not crash on the second?

My code works fine with ::New() before each use.

TIA for any help!
