A shoe tree for one shoe includes a main body having a front end formed with a vamp support portion and a rear end formed with an upwardly extending rising portion and having a first side formed with a first side support portion and a second side formed with a second side support portion. A fingerprint collation program is proposed, in which data outputted from a fingerprint reading sensor is classified into predetermined patterns according to data of a maximum threshold value or more, data of a minimum threshold value or less and an amplitude constituted by a difference obtained based on the maximum and the minimum values of the outputted data. Thereafter, the image information and new metadata are rendered available to other processes that use the image information and new metadata. The nanocrystals comprise a material having a property that promotes osseointegration. The encoded bitstream can include a slice table to allow direct access to each slice without reading the entire bitstream.
