Decoded String Field
Once the Sensor has been trained, the Decoded String field should show the characters the software detects
in the image area. If the Sensor does not correctly identify all the characters in the string, you may need to do
some additional training.
Note: The software ignores spaces.
Note: For OCV, if the Decoded string does not match the Expected String, then the Decoded string will
be displayed in red.

The Box Tab
When you capture a reference image using the OCR or OCV tool, these tools use sophisticated pattern
recognition algorithms to box what is estimated to be individual characters in a captured image. In the example
below, the initial image capture finds all the individual characters except the 3 and the 4, which it has incorrectly
boxed as a single character. In the Box tab, you can calibrate image settings so that the software will more
accurately box the characters in a character string.
