[ITK-users] Region of two labelObjects

[Pol Monsó Purtí]

Hello all,

I have two label objects, how can I merge the two BoundingBoxes together so
I know the necessary size of the image? (other than creating it myself by
searching max/min of each dimension)

How come LabelMap doesn't resize automatically when objects are added? It
could.

template< typename TImageType >
void labelObjects2Image(ShapeLabelObjectType* labelObject1,
                   ShapeLabelObjectType* labelObject2,
                   typename TImageType::Pointer& labelMapImage){

typedef itk::ShapeLabelObject< typename TImageType::PixelType,
TImageType::ImageDimension > ShapeLabelObjectType;
typedef itk::LabelMap< ShapeLabelObjectType > LabelMapType;
typedef itk::LabelMapToLabelImageFilter< LabelMapType, TImageType >
Label2VolumeFilter;

*--> region = labelObject1->GetBoundingBox() "+"
labelObject2->GetBoundingBox()*

auto segLabelMap = LabelMapType::New();
segLabelMap->SetRegions(region);
segLabelMap->Allocate();

segLabelMap->AddLabelObject(labelObject1);
segLabelMap->AddLabelObject(labelObject2);

auto label2volume = Label2VolumeFilter::New();

label2volume->SetInput(segLabelMap);

label2volume->Update();
labelMapImage = label2volume->GetOutput();

}

Cheers,

Pol
