In forensics, a imprint or a stain left by a person's lips may be used to assist in identification.
The above image depicts an imprint of a subject's lips, left in red lipstick. Some identifying features to this particular set of lips includes the noticeable vertical grooves in each lip, as well as the characteristic spaces between the lips, as marked in the image.
A particular experiment carried out as an exercise in applying lip-print identification skills was carried out under controlled conditions. Various lip-prints were applied to a sheet of white paper. Each individual lip-print found on the sheet were also impressed upon singular note-cards. The master print sheet was exchanged, along with the note-cards. Using these print-identification skills, prints on the master sheet were given characterizations and had their features examined closely. Following this, the note-card prints were matched with the master sheet prints, with varying degrees of success which I will not discuss in great detail here.

Good description, but maybe you could discuss the activities we did in class.
ReplyDeleteAdd some information on our class experiment!! You could talk about how we traded sheets & tried to identify who's print was who's. This is a great start though.
ReplyDeleteI believe more information would be nice more specifically information on the activities along with some more pictures.
ReplyDeleteThere is a picture, Adiair. I'm sure it just decided not to display itself because of the sorry state of the laptops we're using.
ReplyDeleteAlso, I would have posted more information, but there really is no more information on the subject to post.
