Overview

Veritone Redact’s Object Detection engine works by scanning through your media frame by frame looking for any objects that appear to be a laptop or license plate.

For our license detection, the engine looks for the plate itself and will target either headlights or tail lights if a plate cannot be detected. Laptops are detected by scanning for a keyboard. For any device without a keyboard that needs to be redacted, such as an MBT or a cell phone, you’ll need to apply a User Defined Region (UDR).

How to Run Automatic Object Detection

After selecting the media that you would like to upload into Veritone Redact, simply select “Run Head and Object Detection” and click “Upload”. This will scan your media for heads during the upload process.

If you did not run head and object detection while uploading your media, you can do so from the File Manager Page. Click on the file name on the Redact Homepage to open this page.

Click Detect Heads and Objects on the Video tab. The head detection cognitive engine will commence processing. You can perform other work on the file while waiting for object detection to finish, i.e. add user-defined regions, run audio transcription, etc. or return to the homepage to work on a different file.

Note: Processing times vary based on the size of the file. Cognitive engine processing occurs in the cloud and does not require the browser to be open.

The processing status of the file's head and object detection can be viewed in the Notification Center.

How to Review Object Detection

When object detection processing is complete, enable all automatic object detections and populate the Laptop and Plate/Vehicle timelines. To do this, select the checkbox below Detect Heads and Objects, under the Video panel on the right side.

Auto-detected laptops and license plates are outlined or blackfilled depending on the Preview selection made in the lower left corner of the page. The boxed area represents the area that will be obfuscated once the video is processed for redaction.

Under the Video tab located on the right hand side of the File Manager Page, each thumbnail image represents a single frame of video that contains a detected license plate or laptopstop. To advance the video to the specific frame at which that object appears, click on the corresponding time segment. You can drag the red marker handle on the scrub bar or utilize keyboard shortcuts to advance at different speeds as desired.

How to Delete an Automatic Laptop or License Plate Detection

If there is a false positive or a laptop or license plate that does not need to be redacted, you can simply uncheck the box associated with that specific object.

A detected license plate or laptop must be selected for the redaction mask to display in the video.

Note: If you noticed a laptop or license plate, or in some instances, a partial laptop or license plate due to an obstruction in the media, was not captured by our object detection engine, you will need to draw a User Defined Region (UDR) to redact this. Learn more about UDRs here.
