That kind of video analytics sournds very interesting. My problem isn't doggy-doo but deer. They happen to favor the new buds of roses, pretty much the whole plant on hibiscus and any other plant that my wife actually likes. I've tried the 'turn on the sprinklers' trick but - using only motion - it's either too trigger happy and wasteful or won't turn on until after the meal has been completed...
But if I could recognize deer and water them it would be perfect! The cameras are in place and I get great video of the munching but would love to safely chase them off too.
Not a fan of Mac, and whatever I do needs to fit into a VM on my server. Anything Linux (best) or windows (yuch but workable) would be much better.
OT: my wife thought that putting a pan of deer meal, a salt lick and a large pan of water off the end of our fence on the open space would keep them happy w/out needing to eat the pretty plants. Didn't really work. But a fairly smart coyote started camping out nearby and happily snacked on smaller animals attracted by the feeding station. Oops! I told her not to be upset - just that she was feeding more animals than she planned. For all you males out there...this response was not too well received
