Reducing False Readings

admin November 27, 2012 Image, Settings No Comments

With scanned images it is not uncommon to have noisy documents which can produce false readings. However this can be dealt with using Softek’s software through the methods shown below.

 

1. Turn off barcode types you do not need to read. For example, say
the c53e barcode is of type CODABAR and the barcodes you actually want
to read are of type CODE39 then turn off CODABAR barcodes with
reader.ReadCodabar = false.

2. Unless you need to read barcodes of length 1 then do not set
MinLength = 1 because this increases the chances of a false positive
result.

3. Use the Pattern property to specify a regular expression that the
barcode value must match.

4. Set MinOccurrence = PrefOccurrence = 5. This increases the
threshold for barcode recognition. You can increase this further if
needs be.

 

Still Having trouble? Don’t hesitate to get in touch!
