sharperappearing lines, and below each is a density trace across the respective
line.

Biomedical Image Analysis
In the search for a single measure that could represent the combined eects of
various imaging and display processes, several researchers proposed various
measures under the general label of \acutance" 114, 115, 142, 143, 144, 145,
146].

The Workbook of Darkroom Techniques
Grain is increased slightly. • Make pictures look sharp by using a high acutance
developer. High acutance developers create an illusion of sharpness by
emphasizing any edges that appear in the picture. Where a dark area meets a
light area, ...

The Reproduction of Colour
One such measure is system modulation transfer acutance, or SMT acutance (
Crane, 1964). In making such assessments, allowance has to be made for the
fact that the human eye, as shown in Fig. 18.16, has a maximum response at
about 3 ...
