Random Walks for Interactive Alpha-matting

  title={Random Walks for Interactive Alpha-matting},
  author={Leo Grady and Thomas Schiwietz and Shmuel Aharon},
Interactive, efficient, methods of foreground extraction a nd alpha-matting are of increasing practical importance for digital image editing. Although several new approaches to this problem have recently been developed, many challenges remain. We propose a new technique based on random walks that has the following advantages: First, by leveraging a recent technique from manifold learning theory, we effectively use RGB values to set boundaries for the random walker, even in fuzzy or low-contrast… CONTINUE READING
