  Given a video demonstration, can we imitate the action contained in this
video? In this paper, we introduce a novel task, dubbed mesh-based action
imitation. The goal of this task is to enable an arbitrary target human mesh to
perform the same action shown on the video demonstration. To achieve this, a
novel Mesh-based Video Action Imitation (M-VAI) method is proposed by us. M-VAI
first learns to reconstruct the meshes from the given source image frames, then
the initial recovered mesh sequence is fed into mesh2mesh, a mesh sequence
smooth module proposed by us, to improve the temporal consistency. Finally, we
imitate the actions by transferring the pose from the constructed human body to
our target identity mesh. High-quality and detailed human body meshes can be
generated by using our M-VAI. Extensive experiments demonstrate the feasibility
of our task and the effectiveness of our proposed method.
