Methods were investigated for estimating the poses of human faces undergoing large rotations in depth. Dimensionality reduction using principal components analysis enabled pose changes to be visualised as manifolds in low-dimensional subspaces and provided a useful mechanism for investigating these changes. Appearance-based matching using Gabor wavelets was developed for real-time face tracking and pose estimation. A real-time Gabor wavelet projection was implemented using a Datacube MaxVideo 250 whilst an alternative system for real-time pose estimation used only standard PC hardware.
