RESULTS
In order to show the e±ciency of our method, we
evaluate stability and accuracy of our system by test-
ing 15 samples guitar chords (i.e., 11 general chords
and 4 bar chords) in various di®erent conditions, some
of which are challenging. The reported experiment
was acquired and processed on-line and in real-time
on a Pentium M laptop computer running MS Win-
dows at 1.6 GHz with 1 GB RAM, and two USB
cameras with resolution 320 £ 240 have been used
for capture.
