View-based Location and Tracking of Body Parts for Visual Interaction
A. Micilotta and R. Bowden (University of Surrey)
This paper presents a real time approach to locate and track the upper
torso of the human body. Our main interest is not in 3D biometric accuracy,
but rather a sufficient discriminatory representation for visual interaction.
The algorithm employs background suppression and a general approximation
to body shape, applied within a particle filter framework, making use of
integral images to maintain real-time performance. Furthermore, we present
a novel method to disambiguate the hands of the subject and to predict the
likely position of elbows. The final system is demonstrated segmenting multiple
subjects from a cluttered scene at above real time operation.
