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.
On the Box tab, you can calibrate the following:
• Image Control Parameters on page 232
• ROI Control Calibration on page 233
• Character Settings Calibration on page 235
• Character Connectivity Calibration on page 238
• Thresholding Calibration on page 240
Training List
You can add, load, or import images as a Training List to train character patterns into the Sensor.
