edge detection result and mapping

Hey guys, I'm currently trying out different edge detection in max msp. I've tried out the cv.jit library tools like cv.jit.binedge, cv.jit.canny and I also have tried around X-ray.jit..
My question is what is the best way to get the values out of the edge detected? I was thinking of mapping the result into an audible signal/sound by somehow map the x-axis/vertical into duration/time for each sound, but not sure... I also thought about getting the density of the resulted edges. Probably by scanning an image from left to right and top to bottom?

Thanks
