I’m using the “contour” to do tracking for a multitouch interface project (using vvvv and processing). I have a “displacement” between the coordinate returned by “contour” and what I’m drawing with processing/projecting on the interface.
To correct the displacement I’m thinking to use a parabola equation “A*sqr(X)”. Feeding two “expr” objects with the x and y returned by “contour”.
The problem is that I need to have at least two blobs (detected by “contour”) for getting a value out of “expr”. With only one “expr” returns O
I must be missing something really obvious …
ps: i’m new to vvvv …:-(… but working hard to change that
