WitrynaThese areas are called blobs. To do so, you need to feed an image from the camera to the algorithm. It will then analyze it and output the coordinates of the found blobs. You will visualize these coordinates directly on the image and indicate whether a blob was found by using the red and green LED. 1. Prepare the Script http://www.iotword.com/10307.html
