2.1.0-pre.1

v2.1.0-pre.1

About

This pre-release build focuses on command-line application improvements and API updates.

Details

• Improved error messages from command-line application
  • Note: All values returned from NFIQ 2 are in the range [0, 100]. The code will no longer produce 254 or 255 values to indicate error, but will instead produce an error message.
• Improved handling of images with no or poor resolution encoding in command-line application
• Improved feature value stability across all operating systems
  • Slight modifications to introduce stability to macOS M1 chips
• Improvement and fixes to CSV output from command-line application
• Improved API design (more changes to come)

More Details

• Added ability to resample images from command-line application
• Corrected CSV output from command-line application in several instances
• All non-numeric values are quoted
• Newlines are trimmed from OpenCV exception messages
• Corrected ordering of UniformImage and EmptyImageOrContrastTooLow actionable feedback columns
• Use of OpenCV 4.5.2
• Reduced dependencies, including removing BiomDI
• Assorted "under-the-hood" improvements

Install

• Windows (.msi): Double-click to install and follow prompts
  • Note: If you previously installed 2.0.999.900 32-bit version, you will need to manually uninstall it first due to a misconfiguration in the 2.0.999.900 installer. This will not be necessary for future versions.
• macOS (.pkg): Double-click to install and follow prompts.
  • Note: If you have Mac with an M1 CPU, we suggest downloading the arm64 version below for the best performance.
  • Note: x86_64 macOS 11 version has been tested on both macOS 10.15 and 11, but we are providing OS-specific builds anyway.
• RHEL/CentOS 8 (.rpm): sudo dnf install *el8*rpm
  • Note: You may need to enable the powertools repo with dnf config-manager --set-enabled powertools and EPEL repo (with dnf install epel-release) to find all required system dependencies for the command-line application.
