Digital Image Art Style Transfer Algorithm Based on CycleGAN

Algorithm 2

CycleGAN algorithm.

	BEGIN
	FOR training iterations DO:
	Extract n sample data from the X field {x^(1), …, x^(n)}.
	Extract m sample data from the Y field {y^(1), …, y^(m)} .
	.
	Calculate the discriminator loss of the generated data .
	Optimize the discriminator network parameters.
	Calculate the generator loss of Y ⟶ X
	.
	Calculate the generator loss of X ⟶ Y
	.
	Optimize generator network parameters.
	END FOR.
	END.
