Human Motion Generative Model Using Variational Autoencoder

Yuichiro Motegi, Yuma Hijioka, and Makoto Murakami
Abstract—We present a technique to learn large human motion data captured with optical motion capture system, represent it in a low dimensional latent space, so as to generate natural and various human motions from it. To extract human motion features we use a convolutional autoencoder, and to represent the extracted features as a probability density function in a latent space we use a variational autoencoder. Motion generator is modeled as a map from a latent variable sampled in the latent space to a motion capture data. We stack the convolutional decoder on top of the variational decoder, which can sample a latent variable and produce a motion. As a result, our system can generate natural and various human motions from a 32-dimensional latent space.

Index Terms—Character animation, convolutional autoencoder, motion generative model, variational autoencoder.
