piwall-cvtools

OpenCV inspired tools for working with video walls, especially piwall.co.uk.

prerequisites and installation

opencv 3.1.0 (notes on Gdrive / follow the pyimagesearch process for building from git) matplotlib : on ubuntu apt-get install python-matplotlib common/ : TODO - this is resolved from /home/adam/pd/opencv/opencv-3.1.0/samples/python/ in turn this is unpacked from opencv-3.1.0.zip (76M download from opencv.org)

Status 17/09/2016

• Amended to include data/rotating_wall.mp4 and data/2x2-red-1.jpg and piwall.py updated
• Command line arguments as follows should be reproducible :

/usr/bin/python piwall.py -v rotating

Note that data/ has some real mp4 files and one symbolic linkj, currently pointed at the shorter.

To make shorter versions, the recipe is :

ffmpeg -i rotating_wall.mp4 -ss 00:00:00.0 -c copy -t 00:00:02.0 rotating_wall_2s.mp4

TODO NEXT : add harris corner detection

TODO NEXT :

Step around the problem of integrating everything in one GUI with multiprocessing ?
