Thanks for your replies. I'm just a noob here. Your patch will take me days to understand Yair :)
I am able to extract the coordinates of jit.features now thanks to you Keith.
Let's say I want to save the coordinates of all the feature points of one object once (feature point 1 to the last one taken from a still image?) Later I want to compare the feature points of a new object in my camera view to the saved ones.
What do I need to do this? Do I need to save them in a matrix or something like jit.cellblocks?
What I would like is a match when for instance 80% of the points match the saved ones (with a margin because they never will be exact due to the live input).
