Detailed Description

template<class TFourierSeriesPath, class TSwathMeritImage>
class itk::OrthogonalSwath2DPathFilter< TFourierSeriesPath, TSwathMeritImage >

Filter that optimizes a 2D path relative to an image.

OrthogonalSwath2DPathFilter produces an OrthogonallyCorrected2DParametricPath representation of a path that is optimal with respect to an image and an original Fourier series path (sometimes referred to as an "initial contour"). Usage is a little complex. The input image must be preprocessed with ExtractOrthogonalSwath2DImageFilter (the user may want to smooth the image first). The user should then use the resulting swath image to produce a new "merit" swath image of the EXACT same size as the swath image produced in the preceeding step. Each pixel value in the merit swath image indicates the local merit of having the path pass through that swath index (taking the absolute value of the vertical partial-derivative of the swath image is often a good way to do this). Both the merit swath image and the path used to extract the swath image should then be passed as inputs to this filter which will search through the merit swath image using dynamic programming to find the absolutely optimum (in terms of the swath image) path. itkOrthogonalSwath2DPathFilterTest.cxx provides a good usage example.
