Journal ArticleDOI
Fingerprint enhancement using STFT analysis
TL;DR: A new approach for fingerprint enhancement based on short time Fourier transform (STFT) Analysis is introduced and the algorithm simultaneously estimates all the intrinsic properties of the fingerprints such as the foreground region mask, local ridge orientation and local ridge frequency.
Journal ArticleDOI
Size-Controlled Synthesis of Cu2-xE (E = S, Se) Nanocrystals with Strong Tunable Near-Infrared Localized Surface Plasmon Resonance and High Conductivity in Thin Films
TL;DR: In this paper, a facile method for preparing highly self-doped Cu2-xE (E = S, Se) nanocrystals (NCs) with controlled size in the range of 2.8-13.5 nm and 7.2-16.5nm, respectively, is demonstrated.
Journal ArticleDOI
Efficient Heterojunction Photovoltaic Cell Utilizing Nanocomposites of Lead Sulfide Nanocrystals and a Low‐Bandgap Polymer
TL;DR: While these materials will require appropriate encapsulation and proper disposal to avoid environmental contamination, they represent the best choice to achieve better light harvesting including nearand mid-infrared (IR) wavelengths.
Journal ArticleDOI
Sub-bandgap photoconductivity in ZnO epilayers and extraction of trap density spectra
TL;DR: In this article, hole trap density spectrum is extracted based on the basis of the rate equation model and assumptions for hole capture lifetime and carrier recombination lifetime that are validated by experimental time-resolved photoluminescence measurements of the material under study.
Book ChapterDOI
Fingerprint image enhancement using STFT analysis
TL;DR: A new approach for fingerprint enhancement based on Short Time Fourier Transform(STFT) Analysis, which simultaneously estimates all the intrinsic properties of the fingerprints such as the foreground region mask, local ridge orientation and local frequency orientation is introduced.
