Detection features

Lighting: the landmark detection has been tested under office lighting conditions - ie, under 100 to 500 lux. As the detection itself relies on contrast differences, it should actually behave well as long as the marks in your input images are reasonably well contrasted. If you feel that the detection is not running well, make sure the camera auto gain is activated - via the Telepathe interface - or try to adjust manually the camera contrast.
Size range for the detected Marks:
Minimun : ~0.035 rad = 2 deg. It corresponds to ~14 pixels in a QVGA image

Maximum : ~0.40 rad = 23 deg. It corresponds to ~160 pixels in a QVGA image
Tilt : +/- 60 deg (0 deg corresponds to the mark facing the camera)
Rotation in image plane : invariant
