I need high accuracy for processing bank checks with OCR. Are there any specific dials that we can tune for better results.
Besides, I do not have control on the scanning quality as the check images are uploaded by bank customers.

To check accuracy of the outputs you could analyze whether the suspicious attribute of the charParams tags is set to true (suspicious="1") or to false (suspicious is omitted). If its value is true ("1"), the corresponding character is uncertainly recognized. You could also set the xml:writeRecognitionVariants parameter of the processImage method to true to get additional information such as character recognition confidence (the charConfidence attribute of the charRecVariant tag). The above attributes are available for full-page recognition.
For field-level recognition, the confidence attribute is also supported.
