Detection results on three test sequences,
Highway I
and two real sequences (from left
to right). From the top to bottom are: original images; results of change detection; results after
shadow elimination based on intensity and chromacity features (pixels excluded from further
evaluation are depicted with high intensity); results after shadow elimination based on texture
features (object pixels are depicted as red).

where
TP
and

stand for the number of true positive and false negative pixels, and
the subscript

for foreground. The average values of
η
and
ξ
are included in Table I for comparison.
