12 Jan 2012 level set for image segmentation This Matlab code implements an edge based geometric active contour model without reinitialization. Author: Chunming Li

20 Dec 2011 Efficient Graph based image segmentation A new version of previous program, support color image. Author: Su Dongcai

Sorry folks:
I made a mistake.This code is compiled on msvc6++, windows xp system.

02 Dec 2011 Classic AdaBoost Classifier Weak threshold classifier boosted to strong Classifier with Adaboost Author: Dirk-Jan Kroon

Neatly codes, very nice demonstration

01 Dec 2011 System of linear congruences Solution to Simultaneous Linear Congruences Author: Mike Sheppard

01 Dec 2011 Chinese reminder theorem just for fun Author: Su Dongcai

Mike Sheppard:
Thanks for broaden my eye side. The 'sunzTheorem' poster here has the computational complexity of O(N1+..Nm) using your notation, which means it can only handle small magnitude numbers.

19 Jul 2014 Active contour without edge implementation of a well known level set method, easy to read code Author: Su Dongcai Mr.Tee

respected sir,
Can we use this method in area detection in satellite images?

Dear sir,
i am getting following error
COMPILING:
Error: Could not detect a compiler on local system
which can compile the specified input file(s)

C:\PROGRA~1\MATLAB\R2007B\BIN\MEX.PL: Error: No compiler options file could be found to compile source code. Please run "mex -setup" to rectify.

??? Error using ==> mex at 208
Unable to complete successfully.

Error in ==> test_GraphSeg at 30
mex GraphSeg_mex.cpp

Plz help me. My matlab version is 2007b

Good implementation.

On Linux some modifications:
- change the file seperator '/' by filesep in the test files.

- remove the GLTREE:: in the GLTree.h for the declaration of
void SearchClosest(Coord3D *p,Coord3D *pk,int* idc,double* mindist);
void SearchKClosest(Coord3D *p,Coord3D *pk,int* idc,double* mindist,int k);

- remove the double brackets in the file GLTree.cpp { {step=Maxz-Minz;}}

- change the name of the function for the case sensitive problems in knn_search.m for the DeleteGLTree (the case sensitive problems occur at a few other places)
