Single Image Dehazing and Edge Preservation Based on the Dark Channel Probability-Weighted Moments

Algorithm 1

Algorithm of the proposed method based on DCPWM.

(1)	Procedure DCPWM ()
(2)	//normalizing the original image.
(3)	//computing the minimum values from each color channel.
(4)	//computing the transmission.
(5)	//closed-form framework and soft matting technique.
(6)	PWM ⟵ standard deviation //probability-weighted moments based on the standard deviation for each color channel.
(7)	C (r, g, b) ⟵ log transform //logarithmic transform is applied on each color channel.
(8)	End procedure.
