Multilevel Thresholding for Image Segmentation Using Mean Gradient

Algorithm 1

Pseudocode for global and bilevel thresholding.

(1)	Input: image, bilevel
(2)	Output:
(3)	If is RGB //RGB to gray conversion
(4)	else
(5)	//arithmetic mean //mean of gradient vector
(8)	//first threshold
(9)	//second threshold
(10)	If bilevel is true:
(11)
(12)
(13)
(14)	Else//global thresholding
	//compute probability distribution function
(15)	If
(16)
(17)
(18)
(19)	Else
(20)
(21)
