Chapter 8
Conclusions and Future Research
The main objective of this research is to explore efficient indexing mechanisms for some unimodal traits as well as multimodal biometrics. The outcomes of this research are discussed in Chapter 4 to 8 in this book. In this chapter, some salient features of the research contributions are summarized. This research considers some assumptions, which may raise about the validity of the claim. The threats to validity of those considerations are pointed out. Finally, some future research directions in this area of research are given.
8.1 Dimensionality of Index Key Vector
In biometric data indexing, an important judgment is about the dimensionality of the index key vector. The dimensionality of the index vector ...
