rise to line pairs whose shapes resemble the "finder pattern" of the Data Matrix code. These
are sorted and parsed according to various criteria.
➀
Under Code finder strategy , the detection method for grey-scale edges in the image area
can be selected.
The dynamic method works in defined steps (filter) and uses an edge filter to detect the
grey-scale edges.
The static method uses a binarisation threshold that applies to the entire image to detect
the grey-scale edges.
Gavisync finding the threshold for binarisation using the Gavisync algorithm. This is the
option we recommend.
Threshold permits the setting of a fixed binarisation threshold that is used in place of the
Gavisync algorithm. For this purpose, the checkbox for the Gavisync algorithm
must not be activated.
Notice!
The two parameters mentioned can only be set if you have chosen static as the strategy.
Under Cell sampling strategy , you can choose the method that is used to compute the
threshold within the Data Matrix code found. A distinction is made between static ( Static )
and dynamic ( Dynamic ) strategies here as well.
