anatools.annotations.annotations module

class annotations

Bases: object

Generates annotations given a dataset directory, an output directory and mapping file. The dataset directory must include the Ana annotations, images and metadata folders. Examples of mapfiles are in the example channel at /ana/channels/example/mapfiles/.

bounding_box_2d(image_path, out_dir, object_ids=None, object_types=None, line_thickness=1)

Generates images annotated with 2d bounding boxes for datasets downloaded from the Platform. Optional filter on object_ids or object_types (must choose a single filter).

Parameters

  • image_path (str) – Path to of specific image file to draw the boxes for.

  • out_dir (str) – File path to directory where the image should be saved to.

  • object_ids (list[int]) – List of object id’s to annotate. If not provided, all objects will get annotated. Choose either id or type filter.

  • object_types (list[str]) – Filter for the object types to annotate. If not provided, all object types will get annotated. Choose either id or type filter.

  • line_thickness (int) – Desired line thickness for box outline.

bounding_box_3d(image_path, out_dir, object_ids=None, object_types=None, line_thickness=1)

Generates images annotated with 3d bounding boxes for datasets downloaded from the Platform. Optional filter on object_ids or object_types (must choose a single filter).

Parameters

  • image_path (str) – Path to of specific image file to draw the boxes for.

  • out_dir (str) – File path to directory where the image should be saved to.

  • object_ids (list[int]) – List of object id’s to annotate. If not provided, all objects will get annotated. Choose either id or type filter.

  • object_types (list[str]) – Filter for the object types to annotate. If not provided, all object types will get annotated. Choose either id or type filter.

  • line_thickness (int) – Desired line thickness for box outline.
