Method for constructing a whole palmar dactylogram from partial palmar dactylograms

A non-transitory computer-readable medium storing a program that, when executed by processing circuitry, causes the processing circuitry to perform a method for reconstructing a palmar dactylogram of an entirety of a palm of a hand, the method comprising:

• (a) acquiring a partial palmar dactylogram of a region of the palm of a hand;
• (b) forming an intermediate reconstructed dactylogram by mosaicking the partial palmar dactylogram;
• (c) calculating a value of a quality criterion of the intermediate reconstructed dactylogram;
• (d) repeating the forming and calculating steps as long as the value of the quality criterion is less than a threshold value, in each iteration the partial palmar dactylogram acquired in the acquiring step being rejected;
• (e) determining a region among regions of the palm of the hand not covered by the intermediate reconstructed dactylogram;
• and
• (f) repeating steps (a)-(e) and selecting, in the acquiring step, the region determined in the determining step, as long as the intermediate reconstructed dactylogram does not cover all of the regions of the palm of the hand.
