Do you want to make it smile? One possible approach traditionally is to make use of the manipulation technique in latent space to achieve this. However, often we find that this may produce some errors. In this paper, we propose a new smile manipulation approach using Domain Transfer in Latent Space (DTLS) approach. We define various degrees of smile as a series of domains transfer in the DTLS. Our experimental results show that with this of our approach, manipulated photo shows less errors than traditional method, visual comparison can be found in this paper.enconference paper
