Salient Region Detection by Fusing Foreground and Background Cues Extracted from Single Image

Algorithm 1

Label propagation via boundary nodes.

Input:

 : Row-normalized affinity matrix

 : Set of given boundary nodes’ labels

 : Set of unlabelled nodes

 Initialize, set for and for

 while VAR > threshold do

  for do

  end for

   = var()

 end while

 BG = normalize()

 BG() = map(BG)

Output:

 Regional background probability weight map BG() generate by background labels
