Building

A docker image can be created with

docker build -t opencv .

To get X11, run XQuartz, and forward the ports with

socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
 XDISP=` ifconfig en0 | grep "inet " | awk ' { print $2 } ' ` 

Another usefull command to get a shell in in the docker image is

 docker run -it -e DISPLAY="$XDISP":0 -v `pwd`:/data opencv /usr/bin/tcsh 

To just compute the files

docker run -it -v `pwd`:/data opencv
