blob detection
Jan 15th, 2007, 5:25pm  
Got a question concerning the blob detection-library.
I`m using the library with a cam and have to detect the dark pixels. For bright pixels, for example, with luminosity above 0,2f its working very good. But if i want to detect the dark pixels and i set the rate to, for example, 0,1f or 0,05f it isn`t enough. is there a possibility to detect the dark pixels? (and what is this "f" behind the number for?)

I think there is an option for the blob detection to be made with the dark pixels instead of the brightest pixels.

try this:


theBlobDetection.setPosDiscrimination(false);

instead of

theBlobDetection.setPosDiscrimination(true);
