August Update

[Friction Ridge Image and Features Technology Evaluations]

Hello FRIFTE Friends, 

• ELFT, PFT, SlapSeg will move to run exclusively under Ubuntu 24.04.3 (from Ubuntu 20.04) in the relatively near future, aligning with NIST's face technology evaluations. FRIFTE E1N will also move from 24.04.1 to 24.04.3 to keep up. Pre-release versions of validation packages for Ubuntu 24.04 are available on the respective GitHub pages under the "ubuntu24" branch (ELFT, PFT, SlapSeg, E1N). Please do not submit with these yet, but if you're working on a new submission, please target the new operating system and let us know if you encounter any issues.
  • If you've maintained a modern codebase, there's likely not much (if anything) you'll need to do participate other than updating your operating system.
  • The APIs have not changed. These three algorithms are still slotted to be migrated into the FRIF TE umbrella.
• The first FRIFTE E1N results have been posted: innovatrics+0001
• Two important reminders
  •  In our 1:N evaluations, SearchInterface::load() provides a maxSize parameter. This is NIST telling the implementation how much RAM they can use and still have a little extra for each of the dozens of search processes we fork. It is astonishingly important that implementations not use more RAM than maxSize. If they do, implementations will run out of RAM.
  • We provide “null” implementations as examples of using our evaluation APIs. If you use these as a starting point, please remember to change the functions that hard code information, such as those in getCompatability(). You also don't need to keep "Impl" in the name of your implementation.

Talk soon.
