Release Notes

Discover the newest features and improvements of the latest Celantur Container versions.

Read how to update to the latest version of Celantur Container.

Version 24.10.1

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.

Version 24.08.1

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.

    • In REST API mode, the HTTP requests are not logged anymore.

  • object-detection-v2 model now also supports segmentation masks with --save-mask.

  • KNOWN BUG: The combination of --model object-detection-v2 and --cpu-mode causes error.

Version 24.05.1

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 mainenance (refactoring) and dependency upgrades

Version 24.04.1 (hotfix)

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.

Version 24.03.1

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.

Version 24.02.1

Release on Febuary 20, 2024

  • Improve UX of Container API asynchronous processing.

Version 24.01.1

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.

If you are using API mode, remove the following two lines fromcelantur.sh to avoid an PermissionError:

-v "${PROCESS_DIR}/input":"${DOCKER_HOME}/input"

-v "${PROCESS_DIR}/output":"${DOCKER_HOME}/output"

  • In API mode, the keys in JSON response to POST /v1/file now contain underscore instead of dashes.

    {
  "id": "string",
  "content_type": "before: content-type",
  "anonymized_video": "before: anonymized-video",
  "metadata_url": "before: metadata-url"
}

  • Misc. bugfixes

Version 23.12.1

Release on Dec 7, 2023

  • Improved object-detection-v2 model.

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.

  • 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: Generate segmentation masks with the Celantur container

  • 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.
