A bit unrelated but I'm in a need for some sort of cat deterrent that will spray water at all cats except mine. Also it would be nice if humans were exempted as well. I haven't done the legwork myself yet, but would this be an appropriate project to check out for this? (As for identifying my cat I've been thinking about alternative solutions such as rfid necklace or something but it is quickly getting past 'quick hac…

This would be amazing. Please do a DIY blog if you figure this out. :)

Can it track eye movements? A cheap eye tracker would be awesome so all the window's i'm looking at are in focus.

Sounds like a great idea. I would be a little worried about how often I actually am not looking at the window I am typing in. Though, I suspect there are obvious patterns.

Pyimagesearch is great. I'm just a tinkerer / hobbyist in the computer vision space, but this is a site I come to time and again to get up to speed on topics that just seem harder elsewhere.

true that - a lot of very practical examples and posts on this site ..and python makes them a joy to play with!

edit: fwiw - I've been playing with motion detection / background subtraction https://www.pyimagesearch.com/2015/05/25/basic-motion-detect...

A Bluetooth LE device similar to Tile[1] might be a cheap and reliable signal source in a package small enough to attach to a collar. If you had two Bluetooth receivers on either side of your camera's visual field, you could compare signal strengths during motion and positively identify your cat (assuming feline motion detection is a solved problem).

We released a C/C++ computer vision library (Python binding to follow) earlier this month which let you perform face recognition at Real-time from IoT or Raspberry PI devices. The library is dependency free, cross platform and should compile fine on most modern architectures with a C compiler. https://github.com/symisc/sod

Speaking as someone with limited and theoretical knowledge of computer vision, does CV usually overlap with Optical Character Recognition (OCR)?

I read through the readme and don't recall any references to identifying text, so I was wondering if and where a separation between OCR and CV might exist in the development process?

I don't think you'll find a 'quick hack' but what you're asking is definitely possible as a project.

Check this video out for ideas(guy used ML/servo controlled squirt gun to get rid of squirrels from his bird house) https://www.youtube.com/watch?v=QPgqfnKG_T4

If your use case is archival (running this on many videos stored on disk) as opposed to realtime (running on a live video feed), we built a research tool called Scanner [1] for maximum performance in offline video analytics, e.g. see our face detection example [2].

Yes, CV is always the first pass before character extraction. It envolve a lot of image processing routines including morphological operation like dilation, noise removal, etc. and finally blob detection[1]. All of the preprocessing routines are implemented in SOD.

I find it amazing that we live in a world where such profound tech is purposed for such tasks as this :)
