Natural Matting for Degraded Pictures
Sahana M. Prabhu, Ambasamudram Narayanan Rajagopalan · IEEE Transactions on Image Processing · 2011
A new approach for image matting is proposed based on the Kalman filter, to extract the matte and original foreground, despite the presence of noise in the observed image. Different filter formulations with a discontinuity-adaptive Markov random field prior are proposed for handling additive white Gaussian noise and film-grain noise.
