FingerJetFX OSE
--------------------------------------------------------------------------------------------
Fingerprint feature extractor library, initial contribution by DigitalPersona, Inc. 
digitalpersona.com/fingerjetfx 
--------------------------------------------------------------------------------------------

Overview
--------------------------------------------------------------------------------------------
To use this software, application takes the fingerprint image, and makes one call into 
the FingerJetFX library to obtain fingerprint minutiae data, which can be used with 
industry-standard fingerprint recognition engines.


Platforms
--------------------------------------------------------------------------------------------
The FingerJetFX OSE fingerprint feature extractor is platform-independent and can be built 
for, with appropriate changes to the make files, and run in environments with or without 
operating systems, including 
 - Linux
 - Android
 - Windows
 - Windows CE 
 - various RTOSs

FingerJetFX OSE can run on 
 - general purpose 32-bit and 64-bit CPUs 
 - 32-but microcontrollers (ARM, MIPS amd others)

In addition, FingerJetFX OSE 
 - does not reqire DSPs or co-processors
 - does not use floating point

The library has a very small memory foorprint: 
 - ~128K of codespace (can run from ROM)
 - ~128K of RAM  (actual RAM requirement is the size of the image buffer + 32K)


Performance and Recognition Accuracy
--------------------------------------------------------------------------------------------
The initial contribution by DigitalPersona, Inc. (www.digitalpersona.com) 
has met the required PIV performance thresholds for fingerprint minutiae generation 
in MINEX test (SDK 3F).

See http://www.nist.gov/itl/iad/ig/ominex_test-results.cfm for details.

On an ARM Cortex-M3 150MHz processor, feature extraction takes 0.5 to 1.25 sec. 
On an Intel i7 PC, feature extraction takes 10 to 25 mS on a single CPU core.

The code is provided with extensive set of unit tests to ensure accurate 
and reliable operation in the target environments.


The Sample Application
--------------------------------------------------------------------------------------------
The sample application bin/fjfxSample is a command-line tool that does feature extraction
on 500DPI fingerprint image files in PGM (portable graymap) format and saves the 
fingerprint minutiae data in ISO/IEC 19794-2:2005 format.


Required Libraries 
--------------------------------------------------------------------------------------------
FingerJetFX OSE requires
 - CxxTest - open source test framework
 - STLport - portable implementation of Standard Template Library (STL)
These third party components are included in the folder src/ExternalDependencies for your 
convenience to ensure that the library builds correctly.


Standards and Compatibility
--------------------------------------------------------------------------------------------
The output from FingerJetFX OSE is formatted according to the ANSI INSITS 378-2004 
or ISO/IEC 19794-2:2005 specifications for fingerprint minutiae data.


Building FingerJetFX OSE
--------------------------------------------------------------------------------------------

Run 'make' to build the library and the sample application. 
     - lib/libfjfx.so 
     - bin/fjfxSample

Run 'make check' to build the library, sample application and the unit tests and to test 
the libraries using the unit tests and the sample application.

Run 'make debug' to build debug version of the library and sample application:
     - lib/debug/libfjfx.so
     - bin/debug/fjfxSample 
Note that the debug version is significantly slower than the release version.

Run 'make checkdebug' to build the debug version of library, sample application and the 
unit tests and to test the libraries using the unit tests and the sample application.
