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 that needs to be recognized.
2. If that region contains only text, add a text block with the created region to the page's layout. This can be done by calling the AddNew Method of the LayoutBlocks object and specifying the BlockType = BT_Text.
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.
