Frontal Face Authentication using Variants of Dynamic Link Matching Based on Mathematical Morphology
نویسندگان
چکیده
Two variants of dynamic link matching based on mathematical morphology are developed and tested for frontal face authentication, namely, the Morphological Dynamic Link Architecture and the Morphological Signal Decomposition-Dynamic Link Architecture. Local coeecients which weigh the contribution of each node in elastic graph matching according to its discriminatory power are derived. The performance of the proposed algorithms is evaluated in terms of their Receiver Operating Characteristic and the Equal Error Rate achieved in M2VTS database. The comparison with other frontal face authentication algorithms developed within M2VTS project indicates that Morphological Dynamic Link Architecture with discriminatory power coeecients is ranked as the best algorithm in terms of the Equal Error Rate.

A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for frontal face authentication. Instead of a set of Gabor filters tuned to different orientations and scales, multiscale morphological operations are employed to yield a feature vector at each node of the reference grid. Linear projection algorithms for feature selection and automatic weighting of ...

Abs t r ac t . A very attractive approach for face detection is based on multiresolution images (also known as mosaic images). Motivated by the simplicity of this approach, a rule-based face detection algorithm in frontal views is developed first. Second, a novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for face authentication. More specifically, ...
