Quality ISO/
IEC 15415
According to the standard the grades are whole numbers from 0 to 4, where 0
is the lowest and 4 the highest grade. It is important to note what, even though
the implementation is strictly based on the standard, the computation of the
print quality grades depends on the preceding decoding algorithm. Thus, dif-
ferent data code readers (of different vendors) can potentially produce slightly
different results in the print quality assessment"
Overall Quality
Minimum of all individual grades
Contrast
Range between minimum and maximum pixel intensity in
the data code domain. A strong contrast results in a good
grading
Modulation
Indicates how strong the amplitudes of the data code
modules are. Big amplitudes make the assignment of the
modules to black or white more certain, resulting in a high
modulation grade. It is to note that the computation of
the modulation grade is influenced by the specific level
of error correction capacity, meaning that the modulation
degrades less for codes with higher error correction ca-
pacity
Fixed Pattern
Damage
Degradation or damage of the fixed pattern, or the re-
spective quiet zones, is assessed with the Fixed Pattern
Damage quality
Decode
Always takes the grade 4, meaning that the code could
be decoded
Axial Non-
uniformity
Due to a potentially oblique view of the camera onto the
data code or a defective fabrication of the data code itself,
the width to height ratio can be distorted. This deteriora-
tion results in a degraded Axial Nonuniformity
Grid Non-
uniformity
If apart from an affine distortion the data code is subject to
perspective or any other distortions too this degrades the
Grid Nonuniformity quality
