29 Jul 2010	multimodality non-rigid demon algorithm image registration non-rigid 2D and 3D image registration with demon (fluid) algorithm, extended with modality transf. Author: Dirk-Jan Kroon	What a perfect work~~~ I try it and foud that the gradient of the image is calculated as [My,Mx]=gradient(M); But why you want to inverse the x and y? Since normally we use [Mx,My]=gradient(M); Maybe it is related to your 'Movepixels' function? Your implemntation is based on the additive Demons, do you have any idea to add a compositive Demons? How do we calculate the composition of fields in Matlab? Thanks.

30 Aug 2010	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.	Dirk-Jan Kroon	* Tan Chye Cheah See the example in the help op manually_warp_images. (Note!, tomorrow a whole new version of code will be online)	Comment only

Tan Chye Cheah	Hi Dirk, When i try to run manually_warp_images, I received an error below. Thanks for your help. Error using ==> manually_warp_images>manually_warp_images_OpeningFcn at 60 no images set Error in ==> gui_mainfcn at 221 feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:}); Error in ==> manually_warp_images at 38 gui_mainfcn(gui_State, varargin{:});	Comment only
20 Aug 2010	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.	Dirk-Jan Kroon	*Carl bicubic-interpolation is available if you compile the c-code with compile_c_files. (not implemented in .m file because it would be really slow) If you want to keep track of the forward affine matrix during registration, the best way is to put: M = inv(M); as first line in affine_transform.m and as first line in make_init_grid.m	Comment only
19 Aug 2010	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.	Carl	Hi Dirk I did not find any bicubic interpolation in affine_transform_2d.m but bilinear instead. How to use b-spline interpolation for affine_tranform? Is there any way to calculate the affine transform matrix first rather than its inverse matrix? Thanks, Carl	Comment only
