Locating a signature in a scanned form with Jev 1.14 (TypeSafe) and Microsoft Agent Framework

说明与用途

使用Jev 1.14和Microsoft Agent Framework在扫描表单中自动检测签名的存在与位置，包含实验性图像处理和边界框输出功能。

问题

Determining whether a scanned form is signed and locating the signature is difficult with document agents, leading to failures on signed forms, stamps, and handwritten fields.

结果

The approach enables automated detection of signatures in scanned forms, providing both a probability of presence and precise bounding box coordinates, but remains experimental and should be used cautiously.

工作流

• 1. Prepare an image of the scanned form.
• 2. Create a TypeSafe client and send a system_one request with a Noul question for "Is the form signed?" and a Box question for "the signature on the form".
• 3. Include the model "jev-1.14.0" and the header "TypeSafe-Danger-Zone-Images: true".
• 4. Receive the response containing a probability for the Noul answer and a box with top, bottom, left, right fractions and confidence.
• 5. If using the Microsoft Agent Framework, embed the image in a Message and call get_response with the same questions and options.
• 6. Handle pitfalls: check the Noul presence answer before trusting the Box; use separate questions for multiple signatures; crop large images if the target is small.

证据

Jev 1.14 (TypeSafe AI, October 14, 2026) accepts images and a new Box question type that returns the bounding box of one target in an image.

来源

TypeSafe flags both features as experimental ("Danger Zone"): prototypes only.

来源

No "not found" answer. Box always returns a box, even when the target is absent.
