24 Nov 2011	Local min, max, nearest neighbour Find local minima, maxima, match value in vector. Author: Sergei Koptenko	L, Q	Thank you so much.
28 Sep 2011	Pad array Pad array or image. Author: Sergei Koptenko	roy	How to do this on matlab? zero pad the face image with a five‐pixel thick rim around the borders of the image. show the resulting image. Must be manual codes on script.

24 Jan 2012	Sparse Field Methods for Active Contours Very fast implementation of level sets. 2D and 3D support, written in C++/MEX with MATLAB wrapper.	Anusha	How can I implement this as 3D level set?	Comment only
24 Nov 2009	Sparse Field Methods for Active Contours Very fast implementation of level sets. 2D and 3D support, written in C++/MEX with MATLAB wrapper.	Alex Kararg	Could you please help on how I could use your algorithm with 3D images? I have the x,y,z coordinates of the points. I am kind of new to matlab.	Comment only
10 Jun 2009	Sparse Field Methods for Active Contours Very fast implementation of level sets. 2D and 3D support, written in C++/MEX with MATLAB wrapper.	Shawn Lankton	Thanks Sebastien. The bug is FIXED now.	Comment only
01 May 2009	Sparse Field Methods for Active Contours Very fast implementation of level sets. 2D and 3D support, written in C++/MEX with MATLAB wrapper.	Sebastien Paris	Ok I found the bug. Please add "return newll;" in the end of ll_create() function ... Compile fine with Intel ICC right now (around 41% faster than MSVC for my laptop) Please also compile with the -v option to verbose unused variables and remove them.	Comment only
30 Apr 2009	Sparse Field Methods for Active Contours Very fast implementation of level sets. 2D and 3D support, written in C++/MEX with MATLAB wrapper.	Sebastien Paris	Works fine. Thank you. Do you plan to include "multiphase" version ?. One point Segmentation fault when compiled with Intel compiler, ok with LCC or MSVC ... I'll look inside when I'll have time ...	4
