Microsoft Purview OCR for vertical scan?

Question

May I know if Ms Purview OCR is capable to read vertical. Students claim it is not working.

Answer 1

Hi @Wilson Tsui

Microsoft Purview’s Optical Character Recognition (OCR) capabilities primarily support horizontal text extraction. At this time, vertical text recognition may not be fully supported, which could be why students are experiencing issues.

In related Microsoft OCR services, such as Azure's Form Recognizer, there have been reports of challenges with vertical text recognition. Users have observed that the Read API underperforms in detecting vertical alphanumeric texts, suggesting that the models may not be optimized for such orientations.

Given this context, it's possible that Microsoft Purview OCR might also face limitations with vertical text. To address this issue, consider the following steps:

1. Document Orientation: Ensure that documents are oriented horizontally before scanning. Rotating vertical text to a horizontal alignment could improve OCR accuracy.
2. Alternative Tools: Explore other OCR tools known for better vertical text recognition capabilities.
3. Provide Feedback: Report this limitation to Microsoft Support. User feedback can drive improvements in future OCR functionalities.

If you can share specific examples of the documents or images causing issues, it would help in providing more targeted assistance.
