- Abstract summary: We introduce the Latent Image Animator (LIA), a self-supervised autoencoder that evades need for structure representation.
LIA is streamlined to animate images by linear navigation in the latent space. Specifically, motion in generated video is constructed by linear displacement of codes in the latent space.

- Abstract: Due to the remarkable progress of deep generative models, animating images
has become increasingly efficient, whereas associated results have become
increasingly realistic. Current animation-approaches commonly exploit structure
representation extracted from driving videos. Such structure representation is
instrumental in transferring motion from driving videos to still images.
However, such approaches fail in case the source image and driving video
encompass large appearance variation. Moreover, the extraction of structure
information requires additional modules that endow the animation-model with
increased complexity. Deviating from such models, we here introduce the Latent
Image Animator (LIA), a self-supervised autoencoder that evades need for
structure representation. LIA is streamlined to animate images by linear
navigation in the latent space. Specifically, motion in generated video is
constructed by linear displacement of codes in the latent space. Towards this,
we learn a set of orthogonal motion directions simultaneously, and use their
linear combination, in order to represent any displacement in the latent space.
Extensive quantitative and qualitative analysis suggests that our model
systematically and significantly outperforms state-of-art methods on VoxCeleb,
Taichi and TED-talk datasets w.r.t. generated quality.
