I have a frame, and apply it a grayscale and a thresold function, so I finally get an image in black and white.

How could I know the black or white color amount? Any javascript function to do so? I prefer not to include any extra libraries for that task.

Thanks!

What do you mean with 'frame' - an imageData object, uint8 array or ...? – le_m Mar 15 '17 at 16:41
in your threshold function you should be able to simply count the black and white pixels. – Thomas Mar 15 '17 at 18:17
