19 Feb 2010	AngleAverage Solves problems with taking averages of angles Author: Robert Goldstein	It is a good staff and what I am looking for. many thanks.
19 Feb 2010	pmean.m v1.1 (Sep 2009) MEAN and STD of angles, polar, cylindrical, spherical or cartesian coordinates! Author: Carlos Adrian Vargas Aguilera	It is not accurate. Try this example Say, D = zeros(2,1); R = ones(2,1); D(1) = 330; D(2) = 0; [mD,mR,eD,eR] = pmean(Dpi/180,R); polar(Dpi/180,R,'yo') hold on polar(mD*pi/180,mR,'ro')
15 Oct 2009	CONTRAST CONTROLLER Contrast Adjustment of Images Author: Divakar Roy	Thanks for sharing, but I spent 10 minutes on it, it seems not very helpful. Jichao

11 Mar 2010	non-rigid b-spline grid image registration Registration of two 2D/3D images, rigid and with smooth b-spline grid.	medical imaging Ibrahim	I have used this implementation as a step in one of my analysis systems, could you please tell me the paper that I should reference for this work ?

26 Feb 2010	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	baoyun li	Dr. Zhang: Seems you renitilize level set at each step. However, if not using narrow band, reintilization is very time consumming. Can I reinilized by narrowband and still use your AOS codes? If use narrowband, how should I use AOS? I read the "fast geodesic levelset" paper, but don't understand how to apply AOS on Narrow band. Thanks Baoyun	Comment only
22 Feb 2010	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	Mark Brophy	Hi Yan, thanks very much for the great software. I am using your geodesic active contour model for 3d reconstruction. My problem is that I am having trouble updating the 'g' values on the surface. I have attempted to extract the surface using both Matlab's built-in isosurface and zy_binary_boundary_detection(uint8(phi>0)), but both of these commands only return a subset of the points on the surface. Basically, when I evolve the 3d surface, only a subset of the points 'move', so to speak. Do you know how I might all points on the surface? Cheers, -Mark	5
18 Feb 2010	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme	adel khelifi	Hi Yan Zhang, i'm use Windows system, when I used compile_mex_codes to compile, I met the following errors: Error: Compile of 'ac_tridiagonal_Thomas_dll.cpp' failed. ??? Error using ==> mex at 221 Unable to complete successfully. Error in ==> compile_mex_codes at 1 mex ac_tridiagonal_Thomas_dll.cpp Error in ==> run at 57 evalin('caller', [s ';']); **************************************************************** i'm read this message ""a more complete version of the toolbox can be downloaded from the following link: http://ecson.org/resources/software/_AOSLevelsetSegmentationToolbox.zip "" please help me.

15 Feb 2010	multimodality non-rigid demon algorithm image registration non-rigid 2D and 3D image registration with demon (fluid) algorithm, extended with modality transf.	Dirk-Jan Kroon	*Vijay Denoising the data before registration is not really needed, but when done with an edge preserving filter, it will slightly improve the final results.	Comment only
