3D fingerprint image preprocessing and enhancement

Research output: Chapter in book / Conference proceedingChapter in an edited book (as author)Academic researchpeer-review


Contactless 3D fingerprint data acquired from a range of 3D fingerprint sensors requires specialized preprocessing operations. These preprocessing operations are required to suppress the accompanying noise and to enhance or accentuate the ridge–valley features. This chapter details various 3D fingerprint data formats and representations. Preprocessing operations to recover principal curvature, unit normal vector and the ridge surface directions are detailed in this chapter. Implementation of contactless fingerprint contrast enhancement homomorphic filtering is also explained in this chapter.
