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.

30 Nov 2011 Chinese reminder theorem just for fun Author: Su Dongcai Sheppard, Mike

As an alternative, using my "System of linear congruences" submission (#32856) you can solve more general congruence problems, with Chinese Remainder Theorem being a special case:

sunzTheorem([2 3 2], [3 5 7])
ans =
23

lincon([1 1 1], [2 3 2], [3 5 7])
ans =
23 105

Meaning 23+105*k for any integer k would also be a solution.
