In this report we first describe a background subtraction algorithm based on the use of eigen space decomposition. We then present a method to achive incremental modelling, which allows for faster computation and saving in memory requirements. We discuss the performanceof the algorithm and the issues related to the choice of parametersin details. We also provide a description of a real-time implementation which allows to update a model while being able to operate background subtraction at the same time.
