Abstract:
|
We propose a view-invariant representation of human appearance
in multi-view scenarios consisting in a new set of views that overcome
the view-dependency and moderate occlusion problems of
fixed cameras. First, a 3D reconstruction of the scene is generated,
from which we can track multiple persons in the scenario. For each
tracked subject, we define a set of virtual views by projecting its associated
3D volume. The synthetic views can be generated in convenient
directions to detect and classify a number of gestures useful
in assistive and smart environments. Experimental results of the representation and event detection in a multi-camera environment prove the effectiveness of the proposed method. |
