GONZALEZ, Alejandro  y  PRIETO, Flavio. Face landmarks extraction for anthropometric measures. Rev. ing. univ. Medellín [online]. 2010, vol.9, n.17, pp.139-150. ISSN 1692-3324.

In this research, a technique for the extraction of a 22 face landmarks set oriented to anthropometry applications has been proposed. The technique is based on wavelets Gabor transformation and the Elastic Bunch Graph Matching (EBGM) algorithm. The EBGM algorithm was modified so that the extracted points correspond to face landmarks which are commonly used in face anthropometric measures. Modifications were: some geometric restrictions to initially fit the centers location of the region search, and later for the definition of the region. Results show that the face central points present location errors smaller than a millimeter, which is consistent with the measures in direct face anthropometry.

Palabras clave : facial anthropometry; wavelets transformation; EBGM algorithm.
