Résumé:
Motivated by the growing use of electronic surveillance, this research introduces the use of
the Viola-Jones algorithm, which is known to be efficient in recognition of human faces in
images, changing the object to be recognized to vehicle tires, aiming to detect vehicles in
a scene. This approach divides the process in two steps: training and detection. Training
was done using around 7000 different images of vehicles. For the detection step, work
was done to adapt a face detector to detect vehicles tires. The tire detector was compared
to a face detector that used a reference training for faces from OpenCV library. The tire
detector showed 77% efficiency, whereas the face detector showed 80%. False negative
numbers also showed similar closeness, as 2% for the tire detector and 1% for the
reference face detector.
