Predating test

This can be achieved by successfully completing an online multiple choice exam (Unit 101/102)on the e-Volve exam interface.

The exam consists of 50 multiple choice questions to be answered in 1 hour and 45 minutes.

SQF and Acutance measure perceived sharpness as a function of print or display height and viewing distance using formulas that include MTF, assumptions about viewing distance (often proportional to the square root of the print height, but other options are available) and the human visual system (the human eye’s Contrast Sensitivity Function.

slanted-edge method with a first-principles (sine wave-based) calculation, which can be performed through Image J software.

We welcome comments and feedback, but do not guarantee support in the form of question answering, bug fixing, or improvements (in other words, we don’t have money for support, just good intentions).” Web Site : Jester was the first open source mutation system for Java, but does not appear to be actively developed or supported.

Web Site : Simple Jester is a variant of the original Jester by the same author who describes it as easier to use, but slower .

The licence was later changed to Apache2 to enable the mutator to be used in earlier versions of PIT.

slanted-edge algorithms for calculating MTF/SFR are based on ISO 12233 standard, “Photography – Electronic still picture cameras – Resolution measurements”.

This document describes methods for validating the slanted-edge method for calculating image sharpness (expressed as Modulation Transfer Function, MTF, which is synonymous in practice with Spatial Frequency Response, SFR).

MTF is a measurement of image contrast as a function of spatial frequency.

As such, it is a measure of related to perceived image sharpness in a print or display.

It appears to no longer be actively developed or supported.
