Research Profile

John McDonald’s research interests lie in the areas of computer vision, image processing, pattern recognition, and visual simultaneous positioning and mapping. In the past he has worked on topics ranging from face recognition and facial expression analysis, to 3-dimensional and holographic image processing, and intelligent vehicle systems.  More recently his work has focussed on visual positioning and mapping. This work can be divided into two lines of investigation: (i) building viewpoint independent descriptions of the appearance of an environment and then using those descriptions to recognise new images of that scene, and, (ii) using a live video stream from a mobile (e.g. hand-held or robot mounted) camera as input, inferring the 3D structure of the scene that the camera is viewing, and the movement of the camera within that scene. This second areas is sometimes referred to as visual simultaneous localisation and mapping or vSLAM. Some of the applications of this research include life-long autonomous mobile robotics, augmented reality (i.e. virtual reality over live video streams), and visually assisted user navigation.
