Font Selection: Allows you to select the font to use, to create a new font, or to edit the current font library. New fonts are created from existing font libraries.
Confidence: Allows you to specify the minimum level of character identification confidence required before a character will be read and output.
Character Selection: Allows you to specify the width and height of a character (in pixels) or use Auto Size. Disable Auto Size for more reliable reading.
Connection Strength helps correct for characters that are either touching or are formed by individual dots such as those produced by a dot peen stylus or inkjet printing.
This parameter ranges from -3 (AutoVISION will search for characters that are underprinted or not touching) to 3 (AutoVISION will search for characters that are overprinted or touching).
When set to 0, AutoVISION does not perform any pre-processing (multiple passes of an "erode" function for -3, -2, and -1 or multiple passes of a "dilate" function for 1, 2, and 3), so processing time will be decreased.
Match String: Allows you to specify the string that must be matched for the OCR Tool to pass.
Image Pre-Processing: Makes it easier for the tool to recognize and read characters in an image.
Enable ROI (Region of Interest) Rotation: The OCR Tool can be enabled for ROI rotation by clicking the rotation icon at the upper left of the parameters view.
Status – True/False status of the tool.
Read Text – Raw decoded text.
Number of Characters Found – Number of characters located by the tool.
Match Status – True/False when used with a Match String.
Minimum Character Confidence – Lowest match value for all characters.
Maximum Character Confidence – Highest match value for all characters.
Mean Character Confidence – Mean match value for all characters.
Unknown Character is the character that will be returned from the font reading process when no match can be made within the selected font.
The default: character is ?. For example, if the tool cannot decipher the 'H' in "MICROHAWK", the output string will be MICRO?AWK.
If the string has multiple lines, the Multiline Separator will be inserted into the string between lines.
Min Character Area (Pixels) is displayed only when you disable the Allow Segmented Characters option. This setting specifies the minimum size of a character, thereby eliminating segments that are too small to be characters by themselves. The default setting is 40 pixels.
