28 Jan 2012	B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid.	Alberto Gomez	@Tripp, I have found that bug too, I think it suffice to replace M=[] with M=eye(4). There is however another bug I am afraid. I have not gone deep into the code yet but it seems that, when doing 3D NonRigid registration only 1 direction out of 3 is computed, i.e. the resulting grid only has the estimated deformation in the third component, and components 1 and 2 remain unchanged. Ani hint on how to fix this?	4
19 Jan 2012	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Timothy Cale	Yan: I hope you can help with a compilation issue. I am running (64bit) ubuntu 10.04 (vm on fusion 4.3 on a newish MacBook Pro), and I am having a problem compiling: Upon typing "compile_mex_codes", I get: mex: ac_tridiagonal_Thomas_dll.cpp not a normal file or does not exist. Error using mex (line 206) Unable to complete successfully. Error in compile_mex_codes (line 1) mex ac_tridiagonal_Thomas_dll.cpp Note that I ran "mex -setup", though I have compiled mex files successfully before). It looks like (assuming is see my vm as a "glnxa64"). I have g++ selected, as you indicated in earlier post(s). I am not sure about the flags . . . I am using "gcc/g++/gfortran" v. 4.4.3, while mex is apparently supported with 4.3.4, but I had no problems in previous mex compilations.(I am fairly new to Matlab, let alone mex files.)	Comment only
09 Jan 2012	B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid.	Tripp	Great submission! I believe there is a slight bug in the 3D registration if one does non-rigid registration only. I get the following error: ??? Attempted to access M(1,1); index out of bounds because size(M)=[0,0]. Error in ==> make_init_grid at 63 O_trans(:,:,:,1) = mean(1) + M(1,1) * xd + M(1,2) *yd + M(1,3) *zd + M(1,4)* 1; Error in ==> image_registration>Make_Initial_Grid at 475 O_trans=make_init_grid(Spacing,size(Imoving),M); Error in ==> image_registration at 219 [O_trans,Spacing,MaxItt]=Make_Initial_Grid(O_trans,Spacing,Options,Imoving,M,IS3D); If I had to guess, it seems like M (inverse transformation from rigid registration) isn't initialized in the 3D, non-rigid case. I do not get this error when running 2D non-rigid. I also do not get this error when running 3D rigid + non-rigid.	5

12 Dec 2011	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	xiao zhang	Hi, Yan Thanks very much for sharing. I want to compile the code on Windows. However, it seems like the link given in "readme.txt" --http://ecson.org/resources/active_contour_segmentation.html doesn't work any more. Could you tell me how to access the version for WINDOWS? Thanks.	Comment only
