Emotion Editing in Head Reenactment Videos using Latent Space Manipulation

Description

Video generation greatly benefits from integrating facial expressions, as they are highly pertinent in social interaction and hence increase realism in generated talking head videos. Motivated by this, we propose a method for editing emotions in head reenactment videos that is streamlined to modify the latent space of a pre-trained neural head reenactment system. Specifically, our method seeks to disentangle emotions from the latent pose and identity representation. The proposed learning process is based on cycle consistency and image reconstruction losses. Our results suggest that despite its simplicity, such learning successfully decomposes emotion from pose and identity. Our method reproduces facial mimics of a person from a driving video, as well as allows for emotion editing in the reenactment video. We compare our method to the state-of-art for altering emotions in reenactment videos, producing more realistic results that the state-of-art.
