Latent print analysis, matching, and visualization
LatentSleuth uses a novel method for latent-to-reference matching that fully leverages ridge skeletons, is rotationally independent, and effectively handles distortion caused by “elasticity of skin” and other factors. The end result is a mapping between the latent region of interest (ROI) to a region in each reference print being compared, which allows for allows for comparisons based on a quantitative evaluation of the similarity of the latent and reference prints .

I was skeptical about the software after seeing my first demonstration. I knew that computerized latent print matching algorithms are limited by the availability of encodable minutiae. That was before I discovered Sciometrics’ LatentSleuth. For the first time I’m seeing a software program match fingerprints using ridge tracings in a fashion similar to a human examiner. Actually in some ways Sciometrics is superior to the human examiner. The software doesn’t need to know the orientation of the latent print or the anatomical source. It methodically searches all friction ridge detail for a match (and it doesn’t get tired).
