The aim of the project was to propose a method for reliable detection and extraction of facial features in two and three dimensions. Several 2D methods were attempted – edge detection, intensity scanning, and Gabor transform. The Gabor transform method included much filtering. The edge detection and intensity scanning methods were largely unreliable. The Gabor transform method was highly reliable under controlled conditions, and about 60 reliable under uncontrolled conditions, when it was tested on the Yale Database. 3D methods were attempted, but were never successfully implemented. The 2D aim was largely met by the Gabor transform method. The aim was not fulfilled in 3D. The aim in terms of extraction was fulfilled by an anthropometrical method based on the work of Kwok-Wai Wong et al. 3
