Hello @KenSmith
Sorry I didn't hear from you. I just want to share more details regarding to your question.
There are two products I think may help your scenario.
First one is for the general scenario, Azure Computer Vision OCR Read API- https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/overview-ocr#read-api
If you are extracting signature from forms/ invoices/ receipts, you may want to take a look on Azure Form Recognizer - https://learn.microsoft.com/en-us/azure/applied-ai-services/form-recognizer/concept-custom?view=form-recog-3.0.0#try-signature-detection
I hope this helps and please let me know if you have any questions regarding to the product.
Regards,
Yutong
