coordinates and position of a blob!


Apr 04 2009 | 9:57 pm

Hi there!

I am using blobtrack for the first time, and I want to know the exact coordinates of a blob.
I don’t know how to put the (0,0) in the center of my window and after that how to get the x,y coordinates of the center of the blob recognized.
Any ideas?
I have one screenshot which I hope shows what exactly I want to achieve.
Thanks in advance.

some simple addition/subtraction objects or the scale object should do it, depending on what your screen size is. If you get floats in the range 0. 1., you’d have to scale this to the preview window size.
