What is the Face Index?

Deep Indexer's Face Indexer allows you to assign a unique identifier to people in video and image material, making it easier to translate them into metadata. Face Indexer allows you to cluster and manually label faces in your media archive, so you don't have to upload training material, but can use your historical video assets to build a dataset.

Key Functionality:

Face indexing:
Once faces are detected and recognised, they are indexed, allowing users to search for specific faces or filter content based on who appears in the footage. This creates a searchable database of faces across an extensive collection of media files.
Similarity search:
The Face Index also supports similarity-based searching. When a user provides an image, the system can find other instances where the same or similar faces appear in different media assets, even if the person is not explicitly identified.

The Face Index is the easiest way to manage unknown faces. Each face is automatically assigned a unique ID, allowing you to rename it instantly. Normally in the Deep Model Customizer you would have to upload training material for each person. However, with the Face Index, each face is instantly recognisable without the need for training data.

Accessing the Deep Indexer:

The Face Index is triggered along with the Deep Media Analyser's Face Recognition Module when the user chooses to activate it in the parameter configuration.
To access the Face Index results, the user can use the "Indexes" button - which displays a fingerprint - in the left-hand menu.

How can I trigger the Face Indexing?

Select the Media File: Choose the media file you want to analyze.
Activate the Face Recognition Module: In the left column, select the "Face Recognition" module.
Define the Model & Parameters: Choose the model for analysis from the available options, set the parameters and click the yellow "Add Module" button.
Parameters required for the Deep Indexer:
Enable Index Unknown Identities: Allows the Deep Indexer to assign unique IDs to unidentified faces across all assets. Renaming an indexed face will automatically update previously indexed images and future analysis.
(Optional) Cluster Unknown Identities: Groups unrecognised faces as "unknowns" without assigning IDs. All unrecognised persons remain unnamed.
Start the Analysis: You can either add more modules or begin the analysis immediately by clicking "Start Analysis"

How can I access the Face Indexes?

To access the Face Index, the user can use the 'Indexes' button - which displays a fingerprint - in the left-hand menu.
In the Indexes Collection section you will see all the index collections currently available with their Index Collection cards, these can be either Face Indexes or Speaker Indexes. By default you have one index per type, but you can create multiple indexes per type.

Index Collection Card:

Each Index summarizes the most important information in its Collection Card,
this information features:

Name: Name of the Index Collection
Type: Face or Voice
Date Created
Date Last Modified
Number of Identities in the Collection
Description: User given description of the Collection

By clicking "Open" you access the specific Index Collection.

Resultsview in the Index Collection

Index Results are displayed as cards in chronological order with a small thumbnail and the respective Index number.
By clicking on the Three dots (...) in a card you can edit each Indexed Face:

Edit: Manually naming / labeling the ID for example with its name.
Details: Opening the Thumbnail Image
Delete: Permanently deleting this Index

Note:
Deleting an indexed face does not prevent it from being indexed in the next analysis of the same asset or in the analysis of another asset.

Search Field:

Located in the top bar, the search field includes filter settings for refining your results.

Name field: Enter a name to view results that either match or don't match the entered name.
Labeled (Yes/No): Only find manually labeled results

After adjusting filters, click "Apply" to apply them. Active filters appear in a black box beneath the search field and can be cleared by clicking the X symbol.
