GmImgProc: Life is better with us
Framework
- 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
- Play with the framework
- Otsu1d serial implementation 2.1. For rectangular zones
2.2. Make it work for non-rectangular zones
- Otsu2d serial implementation 3.1. For rectangular zones
3.2. Make it work for non-rectangular zones
- Niblack serial implementation 4.1. Just for rectangular zones
- Image color uniformization
- Otsu1d parallelization with openMP (for non-rectangular zones version)
- Otsu2d parallelization with openMP (for non-rectangular zones version)
- Niblack parallelization with openMP
- Parallelization of image color uniformization algorithm with openMP
- Otsu2d parallelization with openCL
Project documentation
Serial implementation results and documentation(steps 1-5):
Results
- Otsu1d
- Otsu2d
- Niblack
- Color uniformization
- Otsu2d
Code
- compiled with Visual Studio 2005 & Intel c++
- we used an existing private image framework
