Detailed Description

Dijkstra algorithm to compute the graph geodesic.

Takes as input a polyline and an image representing a 2D cost function and performs a single source shortest path calculation. Dijkstra's algorithm is used. The implementation is similar to the one described in Introduction to Algorithms (Second Edition) by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Cliff Stein, published by MIT Press and McGraw-Hill. Some minor enhancement are added though. All vertices are not pushed on the heap at start, instead a front set is maintained. The heap is implemented as a binary heap. The output of the filter is a set of lines describing the shortest path from StartVertex to EndVertex. See parent class vtkDijkstraGraphGeodesicPath for the implementation.

Warning
The input cost image must have only VTK_PIXEL cells: i.e., a 2D image or slice of a 3D volume. A cost function for a gray scale image might be generated by the following pipeline: vtkImageData->vtkImageGradientMagnitude->vtkImageShiftScale wherein the gradient magnitude image is inverted so that strong edges have low cost value. Costs in moving from a vertex v to a vertex u are calculated using a weighted additive scheme: cost = Iw*f(I) + Ew*f(u,v) + Cw*f(t,u,v) where Iw is the weight associated with f(I): the normalized image cost, Ew is the weight associated with f(u,v): the normalized distance between vertices u and v, and Cw is the weight associated with f(t,u,v): the normalized curvature calculated from the vertex t which precedes vertex u, and vertices u and v. All weights range from 0 to 1.
