The generation of templates is the result of a series of software routines to extract relevant features.  Following are the sequential steps used by Agora:

  • Image Crop

  • Directions

  • Binarization

  • Thinning

  • Minutiae Extraction

Image crop

The image is separated from its background.  Special algorithms may be used with images captured with live finger scanners, and with paper based images digitized with a flat bed scanner.   Since the image is cropped, to Agora it does not matter what was the original size of the image provided it was within a minimum size 400 x 400 pixels and maximum size of 832 x 768 pixels
