Make a virtual env. Install requirements.

mkvirtualenv superset
make deps

Followed these steps http://www.learnopencv.com/install-opencv-3-on-yosemite-osx-10-10-x/

Install OpenCV 2 on Mac OSX

brew tap homebrew/science
brew install opencv

Because running in a Python Virtualenv, we need to get access to OpenCV (installed as a system package). This is possible to do by creating a few symlinks.

ln /usr/local/lib/python2.7/site-packages/cv.py cv.py
ln /usr/local/lib/python2.7/site-packages/cv2.so cv2.so

Alternately, could try setting up a Virtualenv with the --system-site-packages flag.

make test

make run

Detect cards

Find all cards in an image:

python vision.py -c find -f images/game/game001.jpg

Analyze features

Analyze a single card:

python vision.py -c analyze -f images/single-card/green-full-oval-1.png

You can pass the --display flag to open a window with images analysis steps.

python vision.py -c analyze -f images/single-card/green-full-oval-1.png --display

It's also possible to pass a directory. vision.py will iterate over all .png images in that directory.

python vision.py -c analyze -f images/single-card/

• add more images, and continue tuning algorithm
• rename fns to better explain the pipeline of steps
  • detection - find card shaped items in an image
  • classifaction - is it a card?
  • feature extraction - given a card, what are its features (shape, number, etc)?

• morphology ex (for estimated rectangle shape of set cards)
