Week 10- Minutiae

 This week has been crazy, getting used to my daughter's new speech and occupational therapy schedule while managing a full-time class schedule. Although I have not been able to conduct more experimentation on my research project, I decided to go ahead and talk about the points of minutiae that I will be looking for when examining the fingerprints I find in the objects tested with cyanoacrylate fuming. 

Minutiae are significant features of a fingerprint, using which comparisons of one print with another can be made. Many types of minutiae can be identified when examining a fingerprint. However, I will be using the following:

- Ridge Ending: the point where the ridge ends suddenly 

- Ridge Bifurcation: the point where a single ridge branches out into two or more ridges

- Ridge Dots: Tiny ridges

- Ridge Islands: slightly more extended than dots and occupy a middle space between two diverging ridges

- Spurs: A notch protruding from a ridge

- Bridges: small ridges that join two longer adjacent ridges

"Compared to other fingerprint features, the minutia point features having corresponding orientation maps are distinct enough to distinguish between fingerprints robustly. Fingerprint representation using minutiae feature reduces the complex issue of fingerprint recognition to an issue of point pattern matching" (Thakkar Minutiae Based Extraction in Fingerprint Recognition).
