Hand pattern used during matching to hyperspectral images. The division into individual (points) areas from V _{w 1} to V _{w 6} is performed automatically. For each area, a number of the finger from V _{w 1} to V _{w 5} and the centre of mass of the wrist V _{w 6} are assigned. In the upper part of the image, there is the brightness pattern sized 100 × 1321 pixels. The distribution and size of the fingers is carried out based on anthropometric data.
