Eyeglasses Lens Contour Extraction from Facial Images Using an Efficient Shape Description
This paper presents a system that automatically extracts the position of the eyeglasses and the accurate shape and size of the frame lenses in facial images. The novelty brought by this paper consists in three key contributions. The first one is an original model for representing the shape of the ey...

The second one is a method for generating the search space starting from a finite, relatively small number of representative lens shapes based on Fourier morphing.
