Custom Metadata

Metadata can be customized as needed using: meta dictionaries:

• As a top-level key for metadata applying to entire frame
• In rois dictionaries, for metadata applying to individual ROIs.

Usage

Adding Frame Metadata

When instantiating a Frame, metadata that applies for the entire frame can be added as an argument.

from allegroai import SingleFrame

# create a frame with metadata
frame = SingleFrame(
    source='https://allegro-datasets.s3.amazonaws.com/tutorials/000012.jpg',
    preview_uri='https://allegro-datasets.s3.amazonaws.com/tutorials/000012.jpg',
    # insert metadata dictionary
    metadata={'alive':'yes'}, 
)

# add metadata to the frame
frame.metadata['dangerous'] = 'no'

Adding ROI Metadata

Metadata can be added to individual ROIs when adding an annotation to a frame, using the SingleFrame.add_annotation method.

frame.add_annotation(box2d_xywh=(10, 10, 30, 20), labels=['tiger'],
                     # insert metadata dictionary
                     metadata={'dangerous':'yes'})
