How to Check if a Signature is Present or not in a Document

Vikas M 60

Hello Guys, i am Using Document Intelligence (Form Recognizer), I want to Check if that Document in a certain field has a Signature or not,

I have Labelled and trained a custom model in Azure AI Document Intelligence Studio,
But while testing it doesn't work
May I know how this can be achieved Or if there are any Other alternatives to achieve this.

Note: I just want to check if anything is scribbled in a particular field

Hi @Vikas M,

Thank you for reaching out again. For scenarios where accuracy is critical, confidence can be used to determine whether to automatically accept the prediction or flag it for human review.

See this documentation: Custom models: accuracy and confidence scores.

I hope it helps! Thank you

Hi @Vikas M,

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

To detect the signatures from documents you need to train by using the Custom template model. Please recheck the model you are using Custom template only.

Firstly, thank you all for helping out here.
I'm seeking some guidance on custom document extraction within Document Intelligence. Specifically, I'm wondering if it's feasible to retrain the model and incorporate a human reviewer when the confidence score of the extraction is below a specified threshold.

Any assistance on this matter would be greatly appreciated.

Thanks in advance,
Vikas M

Hey there Vikas M

thats a great question thanks for using QandA platform

As you have said you already trained the models, you can test it with sample documents to check if it accurately detects signatures in the specified fields. Make sure to provide diverse samples covering different types of signatures and variations.

Review the results generated by the model to determine if signatures are correctly identified in the designated fields. The model's accuracy may vary based on factors such as the quality of training data, complexity of signatures, and document variations.

If the model does not perform as expected**, you may need to iterate on the training process, refine the labeling of signature fields,** or provide additional training data to improve accuracy.

Speakimg of alternatives, If Azure AI Document Intelligence does not meet your requirements even after following everything , you can explore other alternatives such as custom machine learning models trained specifically for signature detection.

I can assure you to get accurate results you have to do a lot of refinements, all the very best If this helps kindly accept the answer thanks much.
