Which step of the ACE-V process requires the examiner to identify any distortions associated with the friction ridges?

Digital imaging is a process through which a picture is converted into pixels.

The identity,number,and relative location of ridge characteristics impart ________ to a fingerprint.

Match the word in Column 1 to its definition in Column 2.Each answer can only be used once. A)A class of fingerprints characterized by ridge lines that enter the print from one side and flow out the other side B)An inkless device that captures digital images of fingerprints and palm prints and electronically transmits them to an AFIS C)A square electronic dot that is used to compose a digital image D)A fingerprint impressed in a soft surface E)A class of fingerprints characterized by ridge lines that enter from one side of the pattern and curve around to exit from the same side of the pattern F)A system of identification of individuals by measurement of parts of the body, developed by Alphonse Bertillon G)A process through which a picture is converted into pixels H)A technique for visualizing latent fingerprints by exposing them to iodine vapors I)Ridge endings, bifurcations, enclosures, and other ridge details which must match in two fingerprints to establish their common origin J)A chemical reagent used to develop latent fingerprints on porous materials by reacting with amino acids in perspiration K)A class of fingerprints that includes ridge patterns that are generally rounded or circular and have two deltas L)A physical change from the solid directly into the gaseous state M)A fingerprint made by the deposit of oils and/or perspiration; it is invisible to the naked eye N)A silver nitrate-based reagent formulated to develop latent fingerprints on porous surfaces O)To emit visible light when exposed to light of a shorter wavelength P)A technique for visualizing latent fingerprints on nonporous surfaces by exposing them to cyanoacrylate vapors; named for the commercial product Superglue Q)A fingerprint made when the finger deposits a visible material such as ink, dirt, or blood onto a surface R)A verbal description of a perpetrator's physical characteristics and dress provided by an eyewitness 1)Anthropometry 2)Arch 3)Digital imaging 4)Fluoresce 5)Iodine fuming 6)Latent fingerprint 7)Livescan 8)Loop 9)Ninhydrin 10)Physical developer 11)Pixel 12)Plastic print 13)Portrait parlé 14)Ridge characteristics 15)Sublimation 16)Superglue fuming 17)Visible print 18)Whorl
