itk::Hessian3DToVesselnessMeasureImageFilter< TPixel > Class Template Reference
[Intensity Image Filters, Objects Related to Tensor Images]

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). More...
