Example results of
the mean-shift tracking
algorithm for four test
sequences.
Left column
:
Reprojected ellipsoid
associated with the person's
right hand.
Right column
:
Moving three-dimensional
points in the scene along with
the tracking result
the ellipsoid associated with the hand does not necessarily correspond to the wrist
but rather to the middle of the hand (cf. second example in Fig.
7.19
).
The average runtime of the Matlab implementation of the three-dimensional
mean-shift tracking algorithm corresponds to 260 ms per tracked ellipsoid on a
2
.
4 GHz Core 2 Duo processor. For a C++ implementation, frame rates around
10 frames per second can be expected for the same hardware.
