v0.4.4

[0.4.4] - 2025-11-26

Added

• Added video support. A video dataset can be loaded from a local folder and inspected in the GUI.
• Added video annotation support to the GUI. Video annotations can be currently loaded and exported only manually.
• Renamed Dataset.add_samples_from_path to Dataset.add_images_from_path.
• Added class balancing with a uniform or the input distribution as target. These options can be set for the AnnotationClassBalancingStrategy.
• Added download_example_dataset utility function to simplify the quickstart experience by removing the need for git clone.
• Added tag_depth parameter to Dataset.add_samples_from_path to automatically create tags from subdirectory names.
• Added labeling support for captions: Add/delete/edit captions from the GUI
• Added similarity metadata calculation to Dataset.

Changed

• Renamed the distribution field of AnnotationClassBalancingStrategy to target_distribution.
• Display multiple captions per image in the Captions view.

Fixed

• Support pyav >= v14 by removing the deprecated av.AVError import.
