How to Perform Signature Detection in VIDIZMO

Signature detection is a process that helps identify and locate signatures within your content. VIDIZMO Vision Indexer allows you to perform signature detection on the files uploaded to your Portal.

Once detected, the signatures metadata generated can be used for various purposes, such as redaction to ensure privacy and security, or enabling easy search for content on your Portal that contains signatures. As of now, signature detection is currently available only for images and videos.

This article outlines how to perform signature detection using VIDIZMO Vision Indexer, including both automatic and on-demand processing, as well as redaction of detected signatures.

Pre-requisites​

  • Ensure the VIDIZMO Vision Indexer is configured and enabled for Signature Detection. For configuration instructions, refer to Configuring VIDIZMO Vision Indexer for Object Detection

  • You need to be part of a group with feature permissions for Signature Detection and the necessary permissions for processing your content, such as Upload and Manage My Content. For more information about feature permissions, see Enable Features in the VIDIZMO Portal

  • To redact detected signatures, you must have the Redaction and Bulk Redaction feature permissions.

  • To perform on-demand processing during upload, Custom Upload must be enabled. Refer to How to Custom Upload Media for more details.

Signature Detection via Automatic Processing​

Automatic processing in VIDIZMO refers to the automatic analysis of content added to your Portal based on the detection types configured in the VIDIZMO Vision Indexer.

If Signature Detection is enabled in your VIDIZMO Vision Indexer configuration, it will automatically process any newly added content for signature detection. If signatures are detected in the content, they will be added as detected objects or insights that you can access on your content's playback page.

Automatic signature detection occurs in the following scenarios:

  • When content is uploaded to your portal.
  • When content is ingested.
  • When a copy of the content is created.
  • When a VIDIZMO Live session is saved and published as a recording.

Let us demonstrate how automatic signature detection is performed on an upload in a Redaction Portal:

  1. Click the + Add New button and select Upload Media to upload new content.

  1. Once the file is uploaded, it will undergo automatic processing. The signature detection will be applied to the content.

  1. After the content is processed, click it to open its playback page to view the detected signatures.

  1. You can see the detected signatures in the Insights tab. In cases of videos, you can click on these detections to jump to the timestamp where the signature appears.

Note: You can also search for content containing signatures using the VIDIZMO Portal search. Simply type signature in the search bar to find all content with detected signatures. For more details, see Understanding Search in VIDIZMO.

Signature Detection via On-Demand Processing​

In addition to automatic processing, you can also perform on-demand signature detection during upload or via the process modal.

On-Demand Processing During Upload​

  1. Ensure that Custom Upload is enabled on your Portal and upload your content. The interface varies depending on which Portal you are using. EnterpriseTube users get the Process tab, while DEMS or Redaction users get Advanced Upload.

  1. Once the file is uploaded, switch to the Process Tab.
  2. Click on Generate AI Insights
  3. Add Signature Detection to the Insights field. You can also add other detection types if needed.
  4. Click Save and Process to begin processing the file for the selected insights.

  1. Back on your Portal library, the file undergoing processing

  1. To see the detected signatures, open its playback page after the processing is complete.

On-Demand Processing from the Process Modal​

  1. To process content already present on your Portal library, click Process from its overflow menu.
  2. You can also perform bulk processing by selecting multiple files and using the Process option from the header menu.

  1. On the process modal, select Generate AI Insights.
  2. Add Signature Detection to the Insights field. You can also include other insights if you wish.
  3. Click Start to begin processing the selected content.

  1. After processing is complete, click the file to open the playback page, where the detected signatures will be displayed.

Redaction of Signatures​

Once signatures are detected, you may need to redact them to ensure privacy and compliance with security policies. VIDIZMO allows you to perform redaction using the following ways:

1. Automatic Redaction of Visual Insights​

You can configure VIDIZMO Vision Indexer to automatically redact visual insights, including signatures using its Automatic Object Redaction Settings, refer to its section in Configuring VIDIZMO Vision Indexer for Object Detection

For information on how to perform automatic redactions, see How to Perform Redaction of Visual Insights using VIDIZMO Vision Indexer

2. Manual Redaction in Studio Space​

Alternatively, you can perform manual or selective redaction of detected signatures using VIDIZMO Studio Space. This allows you to redact specific instances of signatures from your content.

For detailed instructions, refer to Step-by-Step Guide to Using Redaction Tool in VIDIZMO

To learn more about using the redaction features in Studio Space, see Redaction using Studio Space: A Comprehensive Walkthrough.
