A Water-Area Recognition Approach Based on “Tuned” Texture Mask and Cuckoo Search Algorithm

Pseudocode 1

Pseudocode of learning “Tuned” mask based on CS algorithm.

	Begin
	Input training sample texture images
	Set the parameters of CS algorithm and generate initial populations
	Generate “Tuned” mask by using Equation (3), and make convolution with training images and “Tuned” mask
	While (The current iteration does not reach the maximum iteration)
	Compute the fitness value of each bird by Equation (4)
	Lévy flight by using Equation (2)
	Update new position of each bird by using Equation (1)
	If (The fitness value of current position is better)
	Replace the object by the new position
	End if
	End while
	Output the optimal “Tuned” mask according to Equation (3)
	End
