I am working on a project, using python, that will take an image[s] from an online webcam such as this and then be able to apply some edge detection and motion detection. I have the edge and motion detection running if I import an image already saved on the pi.
I can import an image from the terminal with:
wget -nd /pi/Documents/ -A jpg https://www.skikelly.com/sf/liveview/?rand=1234556789
I don't know how to put that in a script though.
