[jitter] cv.jit tracking - LED's

Dear all - 

i have made a patch that tracks two LEDs and displays the location of the LED's in a window. I have been able to output the x and y coordinates for each blob (I'm using cv.jit.blobs.centroids so that the loargest blob will be Blob 2 and the second largest blob will be Blob 2.

I am using 4 LED's in total;  1 LED by itself and the 3 other packed together in a triangle formation. To stop the patch seeing there 3 LED's as 3 objects, is there a way I can make these 3 LED's appear as one big LED - can you refract the light using some type of liquid (clear glue?) put over all 3 LED's?

Regards

Stuart
