22 Nov 2009	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Yan Zhang	Hi Alex, The problem has been fully discussed before, please see the previous comments for the details. In brief, go to the source file ac_distance_transform_3d.cpp, and get rid of the string in std::exception.	Comment only

12 Nov 2009	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Khin	Hi Yan Zhang, When I read your 'test_ChanVese_model_3d.m' and 'test_hybrid_model_3d.m', I have a problem that cannot read head_ct.mat file. It's showing error "??? Error using ==> load Unable to read MAT file head_ct.mat. File may be corrupt." is it because of version different? I am using Matlab 6.5 please advise. thanks	Comment only
27 Oct 2009	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Jenny	Hi,Zhang yan.Thank you for your toolbox.I have a problem.I'm trying to use your box to segment my own MRI head datas which are a series of JPEG or DICOM forms.Is your tool possible to segment this form of data.Or I must convert these formats to the supported formats.And how to?Thank you very much!	5
16 Oct 2009	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Yan Zhang	Hi Eran, To answer your first question, let' s use u to represent the level-set, normally we use curvature flow to smooth the curve u_t = div(\nabla u/\|\nabla u\|) In my implementation, I do this in two steps: (1) Make \|\nabla u\| = 1 using reinitialization (ac_reinit). (2) With (1) the above equation can be simplified to u_t = div(\nabla u) = \del u (the Laplacian of u) which describes the linear diffusion of the level-set. It's more efficient than solving the more general PDE u_t = div(g \nabla u/\|\nabla u\|) which leads to the answer to your second question --- you should look into the codes in "ac_GAC_model" (AOS implementation for geodesic active contour) that tells exactly how to integrate edge information.
