HELP with blob detection and jitter scissors

I have divided the video from the webcam into 16 sections using jit.scissors. Now I am trying to use cv.jit.touches on each of the sections so that I can detect blob touches in each different section independently. The idea that from each I can then trigger other events.

However, if I use cv.jit.touches before jit.scissors I get the entire webcam image being blob detected and not the different sections independently. If i use cv.jit.touches after jit.scissors I seem to get no blob detection happening at all in the one section that I have attached it to as an example.

Please take a look at my patch and shed some light on where I am going wrong if you can please and suggest possible solutions or alternative methods. Thank you :)
