NIST logo   Slapseg04 Logo  API Specification   The Slap
Fingerprint Segmentation Evaluation 2004 will investigate the
accuracy of fingerprint image segmentation systems for use with
multi-finger slap images.  The segmentation application to be
tested is assumed to run on Windows 2000 or Red Hat Linux 7.2,
on x86 platforms. Other options must be approved by the Test
Liaison. The application must have a command-line interface as
specified in this document; no other user interface is
permissible.  The segmentation application must be capable of
taking as input either a Wavelet Scalar Quantization (WSQ)
compressed slap image, or an uncompressed raw slap image, and
outputting up to four uncompressed raw segmented images, each
corresponding to one of the individual fingers pictured in the
slap. It is recommended that the segmentation application return
segmentation quality values, indicating the likelihood that that
image was correctly segmented.  1 Application Inputs  1.1 Slap
