Question

Is there a way to recognize a part of an image instead of the whole image?

Solution

1. Create a region object for the part of the image you want to recognize.
2. If the region you want to recognize contains only text, add a text block with the created region to the page's layout.
3. If the region contains something other than text (images, noise that was not removed during image preprocessing, barcodes, etc.), call the AnalyzeRegion method of FRPage object.
4. Call the Recognize method of the FRDocument object.
