What are the details in the fingerprint?
Ridge bifurcation is defined as The point at which a ridge bifurcates or branches into a branching ridge. These features are collectively referred to as details. Most fingerprint extraction and matching techniques limit the feature set to two types of details: ridge ends and ridge bifurcations, as shown in Figure 3.
What is detail extraction?
1 Unthinned Binarized images Most fingerprint minutiae extraction methods are A thinning-based skeletonization process converts each ridge to one pixel wide. Detect minutiae points by locating endpoints and bifurcation points on the refined ridge skeleton based on the number of adjacent pixels.
