Colorization based on soft segmentation
Hyung-Il Koo, Nam-Ik Cho · Journal of Electronic Imaging · 2011
This paper proposes a new colorization method based on the chrominance blending. The weights for the blending are computed by using the random walker algorithm, which is a soft segmentation technique that provides sharp probability transition on object boundaries. As a result, the proposed method reduces color bleeding and provides improved colorization performances compared to conventional ones.
