Hand written signatures are not getting detected in form recognizer custom extraction template models, we are having a requirement to ocr a JPG image, and crop the signature part, store it . Please suggest if it can be done in form recognizer, or does any other Azure services has this capability. We are using custom extraction template models and sometimes signatures are not getting detected in it.

    Hi @Sriramsubramaniyan Nadarajan,

    Thank you for reaching out to Microsoft Q&A forum!

    If you are using custom extraction template models and signatures are not getting detected, you can try the following:

    1. Ensure that the signature field is labeled correctly in the training dataset. Use the "Signature" type label to label the signature field.
    2. Use the "Draw region" command to create a rectangular region at the expected location of the signature.
    3. Select the drawn region and choose the "Signature" type label to assign it to your drawn region.
    4. If your custom model is not performing well, you can improve it by adding more high-quality training data.

    Form Recognizer can detect handwritten text, but detecting signatures accurately may not be possible in all cases. However, using a custom extraction template in Form Recognizer may be the best option for detecting signatures.

    I hope you understand! Thank you.
