Detailed Description

template<typename TPixel>
class itk::Hessian3DToVesselnessMeasureImageFilter< TPixel >

Line filter to provide a vesselness measure for tubular objects from the hessian matrix.

The filter takes as input an image of hessian pixels (SymmetricSecondRankTensor pixels) and preserves pixels that have eigen values $\lambda_3$ close to 0 and $\lambda_2$ and $\lambda_1$ as large negative values (for bright tubular structures).

$| \lambda_1 | < | \lambda_2 | < | \lambda_3 |$

Notes:: The filter takes into account that the eigen values play a crucial role in discrimintaitng shape and orientation of structures.

Bright tubular structures will have low $\lambda_1$ and large negative values of $\lambda_2$ and $\lambda_3$ .
Conversely dark tubular structures will have a low value of $\lambda_1$ and large positive values of $\lambda_2$ and $\lambda_3$ .
Bright plate like structures have low values of $\lambda_1$ and $\lambda_2$ and large negative values of $\lambda_3$
Dark plate like structures have low values of $\lambda_1$ and $\lambda_2$ and large positive values of $\lambda_3$
Bright spherical (blob) like structures have all three eigen values as large negative numbers
Dark spherical (blob) like structures have all three eigen values as large positive numbers

This filter is used to discriminate the Bright tubular structures.

virtual::itk::LightObject::Pointer itk::Hessian3DToVesselnessMeasureImageFilter< TPixel >::CreateAnother ( void ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<typename TPixel >

void itk::Hessian3DToVesselnessMeasureImageFilter< TPixel >::operator= ( const Self & ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
