Hi, it is in Section 3 of this paper. http://webee.technion.ac.il/people/anat.levin/papers/Matting-Levin-Lischinski-Weiss-PAMI.pdf We use the term confidence since the lambda parameter can be different for each pixel. This is useful when using closed form matting to refine an initial alpha matte obtained from another method that also returns the 'confidence' of it's prediction. Pixels with higher confidence are prioritized during the closed form matting optimization.

why the solution of (laplacian + confidence)x=prior satisfy the scribbles , and make the cost function minimal? the confidence makes me confusion...
I didn't see the implementation details in the paper. Could you please explain it? Thanks!
