[MS-1215] Using Full-Res image for OCR in MF-ID

[alexandr-simprints]

JIRA ticket
Will be released in: 2025.4.0

Root cause analysis (for bugfixes only)

First known affected version: 2025.4.0

Initially, SID analyzed heavily-compressed frames from the camera feedback stream to run OCR. While OCR capabilities proved to be great, the resulting image was not up to expected quality. This made it hard to verify that the OCR readout was correct, refer to the image below:

Notable changes

• SID now captures a full-res image as often as it can and runs OCR on the captured images.
• Number of required image captures reduced from 5 to 3 to make the OCR step fast enough.
• Preview images are now clear, and makes it easier for user to confirm whether the OCR readout was correct

Testing guidance

Usual Mf-ID scanner testing protocol. Scan any supported document with OCR scanner.

Additional work checklist

• Effect on other features and security has been considered
• Design document marked as "In development" (if applicable)
• External (Gitbook) and internal (Confluence) Documentation is up to date (or ticket created)
• Test cases in Testiny are up to date (or ticket created)
• Other teams notified about the changes (if applicable)
