Investigating the Relevance of Graph Cut Parameter on Interactive and Automatic Cell Segmentation

Algorithm 1

Cell segmentation using Equation (6).

(1)	Require: I grey scale image
(2)	Output:
(3)	Build graph G from
(4)	for each node a in G
(5)
(6)	Determine a’s a–O edge weight (Figure 1) using the data term in Equation (6)
(7)	Determine a’s a–B edge weight (Figure 1) using the data term in Equation (6)
(8)	end for
(9)	for each node a in G
(10)	determine a’s a–b (neighbourhood) edge weight (Figure 1) using the smoothness term in Equation (6)
(11)	end for
(12)	Use algorithm in [21] to partition G into foreground (O) and background (B) to give
