Human Motion Tracking with a Graph Structure in Latent Spaces

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a novel approach to track human motion with a monocular video. In a conventional tracking system based on particle filter, it is very challenging to track a complex human pose with high dimensional freedoms. A typical solution to this problem is to track it in a low dimensional latent space, e.g. Gaussian Process Dynamical Model (GPDM ). In this paper, we extend the GPDM model into a graph structure (called GPDM graph) to better express the diverse dynamics in human motion, where multiple latent spaces are constructed and connected with each other appropriately. Based on the GPDM graph model, we can track human motion with a monocular video, where the tracking errors are only about 10\% of those by the conventional particle filter.
