The minimum confidence value compares the accuracy of the element found on the document to a defined anchor.
To ensure that you set the correct confidence, test several different examples of the document type.
You can manage the confidence for the different anchor types as follows:
- Structural anchor
Confidence is available only when the Can intersect border option is cleared.
- Graphic anchor
By default, the confidence is set to 70%. Graphics having 70% of their pixels positioned like those of the anchor image are found by the algorithm. For the best results, use the default setting.
- Text anchor
If you determine that anchor text with ten letters has a 90% confidence, the algorithm finds all words that match the recognition results in the anchor zone and have nine to eleven letters.
- Locator anchor
- If you determine that the input locator result has a 90% confidence, the anchor is found on the document. For the best results, use the default setting or higher.
