Fingerprint Verification Using Correlation Filters

2003
In this paper we investigate the use of correlation filters for fingerprint verification. Correlation filters have advantages such as their built-in shift invariance, closed form expressions, graceful degradation, and their ability to trade off discrimination for distortion tolerance.

Multiresolution correlator analysis and filter design

Applied Optics, 1996
The concept of multiresolution optical correlators is formally introduced. A mathematical analysis is performed for a generalized multiresolution correlator that emphasizes the roles of both input and filter spatial light modulator resolutions. Conditions are derived for overlapping and nonoverlapping correlation orders.

Adaptive Multi-class Correlation Filters

2016
Correlation filters have attracted growing attention due to their high efficiency, which have been well studied for binary classification. However, by setting the desired output to be a fixed Gaussian function, the conventional multi-class classification based on correlation filters becomes problematic due to the under-fitting in many real-world ...

Incoherent diffraction correlator with a holographic filter

Applied Optics, 1979
An incoherent optical method for spatial frequency filtering is considered, based on the principle of diffraction in spatial incoherent monochromatic light. Such a method is shown to be possible in an incoherent diffraction correlator with a holographic filter.
