TECHNOLOGY FOR THE DETECTION, CAPTURE & ENHANCEMENT OF FINGERPRINTS

 

Digital Enhancement (of fingerprints)

 

Once a fingerprint has been captured in digital form it is possible to improve the ridge detail and visibility of the print using a variety of processes.


The Foster + Freeman DCS 4 fingerprint capture and enhancement workstation provides:

Image integration to improve the contrast of weakly fluorescent prints

Extended depth of field. A technique to combine multiple 'un-focussed' images to create a single focussed image.

Enhancement filters a variety of filters can be used to remove noise and improve image clarity

Local histogram equalization and de-speckle to improve image clarity

Background subtraction to reduce the visibility of an image background

Fast Fourier Transform (FFT) to eliminate unwanted background form an image
