A method of determining face sub-spaces. The method comprises making initial estimates of the sub-spaces, for example lighting, pose, identity and expression, using Principle Component Analysis on appropriate groups of face s. The method further comprises applying an iterative algorithm to image coding s to maximise the probability of coding across these non-orthogonal sub-spaces , obtaining the projection on each sub-space, and recalculating the spaces.</S DOAB> |
