This report presents two colour tracking techniques developed for use in a real-time interactive motion capture system. The aim of these trackers is to remove the need for special clothing and markers in these systems. The first colour tracker, designed for simplicity and robustness, tracked colours using a static colour model for each of the objects. The second colour tracker, designed to adapt and adjust for colour changes, tracked colours using a dynamic colour model for each of the objects. The dynamic model used the movements of colour in colour space to correct the model to help correctly locate the object.
