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
20 Sep 2009	2D/3D image segmentation toolbox 2D/3D image segmentation using level-set based active contour/surface with AOS scheme Author: Yan Zhang	Could you provide your paper? I try to get your paper online, but it seems I can not. thanks
20 Sep 2009	Hessian based Frangi Vesselness filter Enhancement of Vessel/ridge like structures in 2D/3D image using hessian eigen values Author: Dirk-Jan Kroon	That is great, many thanks for sharing, all the forks. I am wondering whether somebody here uses a similar idea to obtain fiber orientations from 2D/3D images. I guess it uses the eigenvectors and eigenvalues of gradient matrix of the input images.
14 Sep 2009	color Image Segmentation Segments a color image into regions. Author: Athi	why I have the following error, I do not have Image Processing Toolbox? ??? Undefined function or method 'kmeans' for input arguments of type 'double'. Error in ==> colImgSeg at 81 fusedMap = kmeans(inImg_1D,nClass, 'EmptyAction', 'singleton'); Error in ==> SampleUsage at 18 outImg = colImgSeg(inImg, nBins, winSize, nClass);
23 Aug 2009	jpeg2avi This MATLAB script creates animated avi-movies from a series of single frames (jpeg-images). Author: Peter Knott	good, thanks

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

17 Nov 2009	Hessian based Frangi Vesselness filter Enhancement of Vessel/ridge like structures in 2D/3D image using hessian eigen values	PX Chiu	This seriously looks like great stuff, unfortunately, I can't get the c file to compile.. icc: command line warning #10157: ignoring option '-w'; argument is of wrong type icc: error #10104: unable to open 'all' mex: compile of ' "eig3volume.c"' failed. Any help?? Thx in advance!	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
11 Nov 2009	non-rigid b-spline grid image registration Registration of two 2D/3D images, rigid and with smooth b-spline grid.	Chao Li	Hi Dirk, excellent code. One trivial thing I'd like to report is that: in deciding max refinements steps (e.g., line 255 in 'register_image.m, Version18e'), its better to define the lower bound of MaxItt to account for small images.
