02 Dec 2010 Accurate Fast Marching Multistencils second order Fast Marching 2D and 3D including rk4 shortest path and skeletonize Author: Dirk-Jan Kroon

My i ask a question: I prceed the codes as following, but the shortestpath is not finded. What is the reason?
My testing code:
SourcePoint = [26; 100]; %Starting point
F = zeros([101 101]);
F(9:27,10:12) = 1;
F(25:27,12:100) = 1;
SpeedImage = F*1000+0.001;
[X Y] = ndgrid(1:101, 1:101);
T1 = sqrt((X-SourcePoint(1)).^2 + (Y-SourcePoint(2)).^2);
tic; T1_MSFM2 = msfm(SpeedImage, SourcePoint, true, true); toc;
figure, imshow(T1_MSFM2,[ ]); colormap gray;
hold on, plot(ShortestLine(:,2),ShortestLine(:,1),'g')
