Face localization based on the morphological multi-scale fingerprint
Bogdan Raducanu, Manuel Graña · 2002
We propose the use of morphological multi-scale fingerprints (MMF) for face localization. The MMF is computed as the local maxima and minima preserved up to a certain scale in a multi-scale analysis based on morphological erosion and dilation. This approach belongs to a class of global image feature extraction approaches, that can be combined with others to ensure robust face localization. No structural relationships between face elements is taken into account. We compare this approach to the eigenface approach to face detection with clear superior results.
