Optmizing target detection and tracking stability

1- improve contrast

2- avoid repetition

3- check the target histograms in photoshop

4- measure scale for tracking by dividing your camera-to-target distance by ~10: 20 cm wide target would be detectable up to a distance of about 2 meters (20 cm x 10)

5- check the target in gray scale

6- avoid curved shapes
