I'm working on Microsoft Surface 1.0 and working with leds to create a pen for tabletops. My question is, how can i set the minimum size of a blob that can be recognized by the surface?
I mean, if I've thresholded the RAW image of surface cameras and show just the LED i want to be recognized and saved into a CircleF[] array, can I create a contact giving the coordinates of the circle I've saved?.
The point is, when the LED touch the surface, the blob disappear because is too small so it can't be recognized.
There is no supported way to customize this
