Color accuracy* when used with an SFRplus that contains the optional color pattern, located above the central square.Tonal response* (again, with less detail than Stepchart no noise statistics).Distortion (differing detail in different modules best with SFRplus and eSFR ISO.Other results, not derived from slanted-edges are covered in Part 4. Sharpness, expressed as Spatial Frequency Response (SFR), also known as the Modulation Transfer Function (MTF), can be displayed in several ways for individual edges or from the entire pattern,.It also covers text output (CSV and JSON) files. This page covers results that are derived from the slanted-edges (i.e., not from grayscale, color, or wedge patterns). The user does not need to manually select Regions of Interest (ROIs). Imatest Rescharts slanted-edge modulesperform highly automated measurements of several key image quality factors using specially-designed test charts.
