Motion tracking patches

I’m working on a patch to track human body movements to obtein a human responsive video projection.I’m working with freeframe plugin Contour and with backgroundsuppression from Marc_S i would like to try the collision background patch and i guess that also other modules from userpageFrank would be very usefull, since the download links are not available anymore, i wonder if it is possible to share again the files somewherelse on the site.
tnx to all the users and developers for sharing their work!
