This dataset contains the LQMetric and OpenLQM quality component values for the latent impression distal phalanx images of NIST Special Database (SD) 302h. OpenLQM is an open-source reimplementation of LQMetric, designed to keep computed values between the two software applications as identical as possible. All images of SD 302h were run through both the version of LQMetric included with Universal Latent Workstation v6.6.7 and OpenLQM v1.0.0 on a machine running Windows 11. The complete output for each software is available separately. For simplicity, the small number of Overall Quality values that were different between the two software applications is highlighted in a separate file.
