An Alternative Matting Laplacian

This package contains the code described in:

[Pitie16] An Alternative Matting Laplacian. F. Pitie, (2016)
          In International Conference on Image Processing (ICIP'16), September.

This paper offers an alternative formulation to the Matting Laplacian proposed in [1].

Please cite our publication when using the code.

Send an email to fpitie@mee.tcd.ie if you want more information

Example

Run the demo

>>> demo
input image input alpha estimate (using [2])
estimated alpha
estimated a (rescaled) estimated b (rescaled)

The image is taken from the alpha matting evaluation website [3].
