Confidence: Allows you to specify the minimum level of character identification confidence required before a character will be read and output.
Character Polarity: Allows you so specify Dark Characters – black characters on a white background – and Light Characters – white characters on a black background.
Min./Max. Character Size: Allows you to configure minimum and maximum character width and the minimum and maximum character height limits.
Scaling Factor – If a symbol is very large or very small, adjust Scaling Factor to make the character height 30 pixels tall – the best height for the algorithm. For example, if a character is 60 pixels tall, set Scaling Factor to 0.5.
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.
IntelliText OCR improves consistency and readability of a variety of substandard marks, such as inkjet marks or marks on noisy backgrounds. Significant improvements over Standard OCR can be seen in the following areas:
Improved invariance to background noise and uneven illumination;
The ability to read rotated OCR text at any angle;
The ability to handle fixed tilts and slants in characters;
Characters can be scaled up or down to make them the optimal size for reading;
The ability to create a variable match string using regular expressions;
The ability to set character width and height to resolve segmentation issues.
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.
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.
Discard Boundary Characters ignores characters that touch the search box.
Character Slant Detection turns on if characters are expected to slant heavily to the right or the left. Detection is better for non-slanted characters when Character Slant Detection is turned off.
Single Line Detection turns on when there is only a single line of characters. This helps optimize character segmentation for difficult symbols. Often the best option for difficult symbols is to add one OCR Tool per line and then to use the String Format Tool to concatenate the strings into a single string.
