Efficient Graph based image segmentation

A new version of previous program, support color image.

Description

This is an implementation of [1]. The result is slightly different from website[1], because we apply adjacent neighborhood rather than K nearest neighborhood. The following is an example usage:
%complie:(only once)
GraphSeg_complie
%Read an image
img = imread('images\rice.jpg');
%segmentation
[L, contour] = graph_segment(img, 1, 3, 100);
%display result
subplot(2, 1, 1), imshow(img), title('original image'); subplot(2, 1, 2), imshow(label2rgb(L)),title('segmented result');

Hello,
 
You write on the updates that your version on 06 Dec 2010
"supply compling m-file make it independent to the operating systems". I work with a macos operating system and i tried to compile GraphSeg_complie, but it doesn't work:

>> GraphSeg_complie
In file included from Graph_seg_gray.cpp:4:
stdafx.h:17:21: error: windows.h: No such file or directory

    mex: compile of ' "Graph_seg_gray.cpp"' failed.

??? Error using ==> mex at 221
Unable to complete successfully.

Error in ==> GraphSeg_complie at 1
mex Graph_seg_gray.cpp c_GraphSeg_gray.cpp public_functions_lib.cpp extract_edges.cpp c_GraphSeg.cpp
Disjoint_set.cpp disjoint_elt.cpp

What i have to do to do it works?
Your work would be a great help to me if i could run it...

Thanks a lot,

Sara

i have the same problem

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