When it is determined that none of the matching metrics exceed the matching threshold value, one of the non-highest ranked images is compared, in a further matching attempt, to templates of the plurality of templates based on the matching metrics.

Abstract: The present invention relates to a powder composition, in particular a fingerprint powder composition for the visualisation of latent fingerprints. Such fingerprint powder compositions comprise carbogenic nanoparticles which, when mixed with a suitable diluent (including any existing or future fingerprint powders), exhibits excitation-dependent emission properties which enable the fingerprint powder compositions and imagable fingerprint impression patterns formed thereform to be imaged in a variety of different colours by simply varying the wavelength(s) of any excitation radiation. As certain backgrounds can render visualisation of fingerprint impression patterns very difficult, having the flexibility to judiciously tune the foreground colour of the fingerprint impression patterns is a significant advantage since it permits instantaneous improvements in visualisation without needing to resort to using a different fingerprint powder.

Abstract: A part of a human body is caused to contact the surface layer of a recording medium over which a plurality of metallic grains with an outside size of 200 nm or less are distributed. Then, secretions from the skin surface of the body part are caused to adhere to the surface layer of the recording medium to take the print of the body part. If light is irradiated to the recording medium, specific optical characteristics resulting from the surface structure of the recording medium are obtained, and therefore the color of the recording medium varies between a region having secretions and a region having no secretions. This renders it possible to record a visible print on the recording medium.
