Abstract: A dual autoencoder includes a first domain encoder for mapping a first domain image into a first latent space, a first domain decoder for reconstructing the first domain image, a second domain encoder for mapping a second domain image into a second latent space, a second domain decoder for reconstructing the second domain image; and a latent space association network for defining a cross-domain relationship between the first domain and the second domain. An image translation method using a dual encoder, may include: taking a first domain image as an input; determining an output condition; if the output condition is the same domain, reconstructing the first domain image by a first domain encoder and a first domain decoder; and if the output condition is the cross domain, reconstructing a second domain image by the first domain encoder, a latent space association network, and a second domain decoder.
