Imatest ISO 12233:2014 E-SFR charts are implementations of the Low Contrast Edge SFR (E-SFR) test chart illustrated in Section 6.1 and Annex C of the ISO Standard Document. The charts come in three versions:

Standard: basic, no extra measurement features

Enhanced: extra squares, wedges, and color patterns when printed with technologies that allow color

Extended: similar to Enhanced, but with a 16:9 aspect ratio, suitable for HDTV and cinema (Note: Works with Matlab esfrChart)
We currently offer these charts in inkjet format, with Enhanced versions available as photographic prints. All Imatest ISO 12233:2014 E-SFR charts are fully compliant with the ISO standard.

The Imatest eSFR ISO module provides highly automated support for the new charts. Additional details below.
