Solution

  • In tables similar to the image you posted, you should be able to find the cells using the IOcrPage.TableZoneManager.AutoDetectCells() method. This method is used in the OcrMultiEngineDemo project that’s shipped with the current version of LEADTOOLS.

    Here’s how you can test it:

    1. Run the OCR Multi-Engine Demo.
    2. Select the OmniPage OCR Engine
    3. Open the image or PDF file that contains the table.
    4. Draw a zone around the table.
    5. Choose “Update Zones…” from the OCR->Zones menu.
    6. In the “Update Zones” dialog, click “Detect Cells” as shown in attached image.
