Hi,
Thanks Rashad for the replay,
This is a overview of my code, the exception is generated after the update
call
//Sample list generator
myListSampleGeneratorType::Pointer sampleGenerator
=myListSampleGeneratorType
::New();
sampleGenerator->SetInput(image);
sampleGenerator->SetInputVectorData(vdreproj->GetOutput());
sampleGenerator->SetThemeKey(GetParameterString("sample.theme"));
sampleGenerator->SetMaxTrainingSize(GetParameterInt("sample.mt"));
sampleGenerator->SetMaxValidationSize(GetParameterInt("sample.mv"));
sampleGenerator->SetValidationTrainingProportion(GetParameterFloat(
"sample.vtr"));
for(MapThemesType::const_iterator itTheme = mapThemes.begin(); itTheme
!=mapThemes.end(); itTheme++)
{
ClassLabelType currentTheme = itTheme->second;
sampleGenerator->SetCurrentTheme(currentTheme);
double maxRecall = 0;
//training OUT
otbAppLogINFO(" random training out");
ListSamplePointerType outTrainingSample = ListSampleType::New();
LabelListSamplePointerType outTrainingLabel = LabelListSampleType::
New();
sampleGenerator->SetOutOnly();
sampleGenerator->SetTakeAll(false);
sampleGenerator->Update();
for (ListSampleType::Iterator itSample = sampleGenerator->
GetValidationListSample()->Begin();
itSample != sampleGenerator->GetValidationListSample()->End
();
++itSample)
outTrainingSample->PushBack(itSample.GetMeasurementVector());
for ( LabelListSampleType::Iterator itLabel = sampleGenerator->
GetValidationListLabel()->Begin();
itLabel != sampleGenerator->GetValidationListLabel()->End();
++itLabel)
outTrainingLabel->PushBack(itLabel.GetMeasurementVector());
//training IN randomly initialized
otbAppLogINFO(" random training in");
ListSamplePointerType inTrainingSample = ListSampleType::New();
LabelListSamplePointerType inTrainingLabel = LabelListSampleType::
New();
sampleGenerator->SetInOnly();
sampleGenerator->Update();
for (ListSampleType::Iterator itSample = sampleGenerator->
GetValidationListSample()->Begin();
itSample != sampleGenerator->GetValidationListSample()->End
();
++itSample)
inTrainingSample->PushBack(itSample.GetMeasurementVector());
for ( LabelListSampleType::Iterator itLabel = sampleGenerator->
GetValidationListLabel()->Begin();
itLabel != sampleGenerator->GetValidationListLabel()->End();
++itLabel)
inTrainingLabel->PushBack(itLabel.GetMeasurementVector());
.......

}//For all themes of the DB
Best,
