= GmImgProc: Life is better with us  =

= Framework =

 * Name: '''GmImgProc'''
 * SVN: https://svn-batch.grid.pub.ro/svn/PP2009/proiecte/GmImgProc

 * Team members: '''Alexandru Stefanescu''' - alexandru.stefanescu1708, '''Alexandra Olteanu''' - alexandra.olteanu
 * Project description: Image processing : binarization with otsu1d, otsu2d, niblack; image color uniformization


== Technologies we use ==

 * [http://openmp.org/wp] (OPENMP)
 * [http://en.wikipedia.org/wiki/OpenMP] (OPENMP)
 * [http://en.wikipedia.org/wiki/OpenCL] (OPENCL)
 * Languages: C++


== Steps ==

1. Play with the framework

2. Otsu1d serial implementation
  2.1. For rectangular zones

  2.2. Make it work for non-rectangular zones

3. Otsu2d serial implementation
  3.1. For rectangular zones

  3.2. Make it work for non-rectangular zones

4. Niblack serial implementation 
  4.1. Just for rectangular zones

5. Image color uniformization

6. Otsu1d parallelization with openMP (for non-rectangular zones version)

7. Otsu2d parallelization with openMP (for non-rectangular zones version)

8. Niblack parallelization with openMP

9. Parallelization of image color uniformization algorithm with openMP

10. Otsu2d parallelization with openCL

== Results == 

 * Otsu1d
 * Otsu2d
 * Niblack
 * Color uniformization
 
 * Otsu2d 


== Code ==

 * compiled with Visual Studio 2005 & Intel c++
 * we used an existing private image framework
