Release on January 13, 2025
Fixed bug that made the Container stop unexpectedly and without logging any errors.
Minor improvements of object-detection-v2 model.
Release on October 31, 2024
Improved overall detection quality of object-detection-v2 model (with a focus on imagery from the US)
Generally higher recall and precision over all tested use cases and scenarios.
Reduced memory usage Lower memory consumption for large images and panoramas due to optimized storage of segmentation masks.
Preserve IPTC metadata in anonymized images Copy over essential IPTC metadata from original to anonymized JPEG images.
Release on August 20, 2024
Improved logging, updated logging format and hid irrelevant log messages:
Logs are colored in STDOUT depending on the log level.
Log level can be set via --log-level parameter.

Release on June 17, 2024
Remove "ghost" detections when object tracking is enabled for video anonymisation.
Fix bug with NVIDIA driver caused by conflicting library versions.
Software maintenance (refactoring) and dependency upgrades
Release on April 7, 2024
Fix bug: 'color' output in metadata JSON is null instead of RGB triplet for --save-mask all and --save-mask instance.
Fix bug: In API mode, response to POST /v1/file does not contain anonymised_url
When API mode starts without --save-mask parameter, retrieving segmentation masks with GET /file/{id}/binary-mask or GET /file/{id}/instance-mask now causes 404 instead 500 error.
Fix bug: In API mode, DELETE /task/{id} does not remove video metadata json files.
Release on March 28, 2024
Improved object-detection-v2 model.
Fixed bug with REST API query parameter naming: Dashes - are now interchangeable with underscores _ in parameter names.
The Docker container now starts by default as user with uid 1000 and gid 1000.
Release on Febuary 20, 2024
Improve UX of Container API asynchronous processing.
Release on Jan 18, 2024
API mode now supports asynchronous processing.
API mode now supports webhooks.
Improved object-detection-v2 model.
In API mode, the -i <input> and -o <output> folders are used to temporary store the input and output data.
In API mode, the keys in JSON response to POST /v1/file now contain underscore instead of dashes.
Misc. bugfixes
Release on Dec 7, 2023
Improved object-detection-v2 model.
Bugfix: Fetching video metadata as JSON returned no detections in certain cases.
Known issue (Fixed in version 24.02.1): In REST API mode and using the object-detection-v2 model, when submitting a video followed by an image an error occurs (500 HTTP response, "Error in ASGI Framework" in Container log). We'll address this issue with a hotfix or in the upcoming release.
Release on Nov 14, 2023 (Bugfixes)
Bugfix: Container API CLI parameters are not overriden by POST query parameters.
Bugfix: Video processing causes crash when video file has no metadata.
Release on Nov 7, 2023

The object-detection-v2 model has been retrained on UK license plates.
Release on Oct 3, 2023
Integrated object tracking for video processing.
Released on October 03, 2023

Several bug fixes and quality of life improvements.
Released: 2022-06-30
Up to 60% faster processing by generating only metadata and segmentation masks By selecting the new “detect” method (instead of e.g. “blur”), the container is running only the inference on images, skipping the anonymization. This results in faster processing times when only metadata or segmentation masks are required.
Size of Docker image reduced by 1 GiB
Several bug fixes and quality of life improvements.
XMP metadata are now cloned into output images:
Keep (stream/track and container metadata) when anonymizing videos
Create (frame-wise) as JSON of anonymized videos
Customizable Blurring The blurring effect can now be customized by setting gradient start and stop value, as well as the kernel size for specific objects. .
File-wise detection thresholds
Set individual detection thresholds per file by specifying face-threshold, person-threshold, vehicle-threshold and license-plate-threshold when using the or .
REST API You can now send and receive images from the container via a REST API. This makes integration into your data pipelines even easier and more convenient:
Generate segmentation masks Create binary or instance segmentation masks for processed images. These mask files can be used for further image analysis and faster processing:
