Hi. I want to detect empty hole in my products. Can Pixy detect it as picture below. Thanks

Hi Phan,
Pixy works best with colorful objects, so I’m not sure it would work well for what you need. If it is possible to include a color inside the hole then it may work.
If you’d like to try other computer vision approaches, some places to start might be the “Hough transform”:http://en.wikipedia.org/wiki/Hough_transform or “convolution matrix”:http://en.wikipedia.org/wiki/Kernel_(image_processing) since it is simple circle detection. Can’t say those will work, but its where I would start.
