The Artvertiser is a small platform designed to track and substitute an image in a video stream (here defined as an 'advert'), live or archival, with another image or video ('artvert'). It has been designed primarily as a 'Product Replacement' application, designed for substituting street advertisements with art. The Artvertiser code was initially developed by Julian Oliver but has since been significantly improved by Damian Stewart - now running on low spec devices such as the Intel 'Atom' Core Duo boards alongside improvements to the tracking. The code builds upon BazAR <http://cvlab.epfl.ch/software/bazar/> and was authored on a Debian Linux system. It is known to compile and run just fine on a 3D capable Ubuntu or Debian system. It should however compile on any Linux system with little effort.
