How to Perform OCR using VIDIZMO Indexer

OCR (Optical Character Recognition) in VIDIZMO allows you to extract text from images, videos, and documents, enhancing their searchability within your portal. Utilizing the VIDIZMO Vision Indexer, you can process your content for OCR detection, extract any detected text, and convert it into searchable metadata within the portal. Additionally, VIDIZMO provides the ability to perform redactions on these detections. Using VIDIZMO's Studio Space, you can selectively conceal sensitive information, such as personally identifiable information (PII), financial data, or other confidential content within your documents, images, and videos. These redacted files are functional and accessible for business use, allowing users to view, search, and interact with them.

Prerequisites​

  • Ensure you belong to a group with feature permissions for OCR Detection. To configure the VIDIZMO Vision Indexer, you also need the App Management feature enabled.
  • For OCR-based redaction using Studio space, you need to be part of a group with Redaction or Bulk Redaction features enabled.
