HISP TZ Data Entry Evaluation

Upload an A-F form block. The Node.js server sends it to the Python/OpenCV parser and returns structured JSON.

You can use files such as Data 1-A.png or Data 1-B.png. If no type is forced, the parser attempts to detect it from the image.

Minimum dark-pixel ratio required to treat an expected bubble as filled.

Useful for test files named like Data 1-B.png. Leave it unchecked to simulate production behavior.
