to diffuse the leds light, you can put it inside a ping pong ball. or take a sanding paper and slightly scratch the leds surface. i also did experiments with crystal ("fake diamonds") glued to the end of the led for better refraction. or you can go and buy extra wide angle leds.
<br>in <a href="http://jit.cv">jit.cv</a> there are several objects to choke or expand blobs. <br>but i think what your trying to do is create a big source (3leds) and a smaller one. yes?<br>for multi blob tracking i suggest u don't use centroids but instead cv. label>

<br>Dear all -<br><br>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.<br><br>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?
