poisson-matting

Python implementation of poisson matting method described in
Jian Sun, Jiaya Jia, Chi-Keung Tang, and Heung-Yeung Shum. 2004. Poisson matting. ACM Trans. Graph. 23, 3 (August 2004), 315-321. DOI=http://dx.doi.org/10.1145/1015706.1015721 http://www.cs.virginia.edu/~gfx/courses/2006/DataDriven/bib/matting/sun04.pdf

This implementation only covers the global poisson matting part of the paper at present.

Requirements

  • python 3.5 or 2.7
  • scipy
  • numpy
  • matplotlib
  • opencv
  • numba (optional for speed up)

Running the demo

  • '''python poisson_matting.py'''

More Information

The jupyter notebook contains more explanation with nice formatting and pretty pictures, also a numpy version of the poisson solve.
