Thank you for your inquiry.
Note that Aspose.OCR allows you to set the Mark Threshold value to determine how leniently or strictly the API will interpret the OMR marks. For more information, open the link Setting Mark Threshold
. Access the FillThreshold
property of the OmrConfig
class and set the threshold value. You have to supply the value ranging from 0 to 1, where 1 correspond to 100%, meaning that all of the pixels in the area must be black for the area to be considered filled.
Please, try the above mentioned solution at your end. In case of issues, be sure to reach us along with sample OMR scanned sheet image and sample code you are using. We will look into it and update you accordingly.
