Face recognition from profiles using morphological signature transform

A new method for face recognition using profile gray-level images based on the morphological signature transform (MST) is presented in this paper. Gray-level image of profile is thresholded to produce a binary, black and white image. The method is based on the successive morphological erosions of the input profile at different resolutions by primary and rotated structuring elements. The areas of successively eroded images are computed for each structuring element at each pyramid level. The obtained set of numbers is arranged into vectors, ordered, and used as a face descriptor. Obtained recognition rates are 90% for the distorted images (synthetic data) and 76.6 % for the unknown profile image of the stored face
