MITRE - Image Quality Evaluation
2
Image Quality from a SineWave or Bar Target (MTF) MITRE developed its MTF application to compute the Modulation Transfer Function of an imaging system using a sinewave target *, or compute the Contrast Transfer Function (CTF) using a bar target. Aliasing is detected and quantified and, for a sinewave, the input/output relation is established. MTF.zip v6.5 executables for Windows & Mac, with source code [8MB] Image Quality from an Edge Target (SFR) MITRE modified existing code to compute the Spatial Frequency Response (SFR) using an edge target, following procedures defined in ISO12233 *. The SFR equals the MTF of an imaging system under certain conditions. SFR.zip v1.4.2 executables for Windows & Mac, with source code [1MB] Image Quality from the Natural Scene (IQM) MITRE developed its Image Quality Measure (IQM) application to directly measure the quality of an arbitrary image, i.e., it does not require imaging a specific target, constant scene, or reference image. IQM (overview.pdf ) is computed from the image's spatial frequency power spectrum. IQM.zip v7.3 executables for Windows & Mac, with source code [4MB] Image Quality of Fingerprint (IQF) IQF is a derivative of IQM, tailored specifically for fingerprint quality assessment. IQF.zip v1.53 executables for Windows & Mac, with source code [2MB] MITRE developed the MTF, SFR, and IQF freeware applications to support performance analysis of fingerprint capture devices and printers for FBI product certifications *, for the FBI's Integrated Automated Fingerprint Identification System (IAFIS *) and the US government's Personal Identity Verification (PIV *) program.
