Image Analysis

The stages of shape decomposition used to extract the feature vectors for the nodes of the grid.

Grid matching procedure in MSD-DLA.

The model grids are shown overlaid on the images in the first column. Deformed grids when a client (i.e., the correct person) or impostors (i.e., a person pretending to be somebody he is not) are shown in the second and third column.

Discriminatory power coefficients for the grid nodes in MSD-DLA

The brighter a node is the bigger discriminatory power possesses. The intensity of the nodes is normalized for visualization purposes.
