[Video] Week 4 Pt. 1 – Blob Detection & Background subtraction

Code used in the video:

Background Subtraction: https://kylemcdonald.github.io/cv-examples/BackgroundSubtraction/

Contour Detection: https://kylemcdonald.github.io/cv-examples/ContourDetection-opencvjs/

Both put together (need to use python simple http server to run, see below): https://github.com/aaronsherwood/sensorsbodymotion/tree/master/browser/blobDetection

Python Simple HTTP server instructions:

See which version of Python you have: python -V

On Windows, you may have to install Python: https://www.python.org/downloads/windows/

First cd to the directory where the sketch is, then:

If Python version is 3.X start your server by: python3 -m http.server
If Python version is 2.X start your server by: python -m SimpleHTTPServer

On windows try “python” instead of “python3”, or “py -3”
