wai.annotations.core 0.1.8

Python library for converting between deep-learning annotation formats.

wai.annotations core module, containing core data structures and basic data loading and preprocessing techniques.

Changelog

0.1.8 (2022-06-21)

• Added new audio domain for classification using suffix -ac

• Added dataset reader for audio files: from-audio-files-sp, from-audio-files-ac

• Added dataset writer for audio files: to-audio-files-sp, to-audio-files-ac

• Added dummy sink for audio files: to-void-ac

• Added ISP for selecting a sub-sample from the stream: sample

0.1.7 (2022-06-13)

• Added discard-invalid-images ISP for removing corrupt images or annotations with no image attached.

• Added batch-split sub-command for splitting individual batches of annotations into subsets like train/test/val. Supports grouping of files within batches (eg multiple images of the same object).

• Added filter-metadata ISP for filtering object detection.

• Restricted maximum characters per line in help output to 100 to avoid long help strings to become unreadable.

• The polygon-discarder now annotations that either have no polygon or invalid polygons.

• Added descriptions to the help screens of the main commands.

• The ImageSegmentationAnnotation class now outputs the unique values in its exception when there are more unique values than labels

• The Data class (module: wai.annotations.core.domain) now outputs a warning message if a file cannot be read; also added LoggingEnabled mixin.

0.1.6 (2022-05-11)

• Image segmentation annotations received new label_images property that returns images per label (as a dictionary); moved from the ToLayerSegments conversion (wai.annotations.layersegments)

0.1.5 (2022-05-09)

• Added dataset readers that generate dummy datasets from images: from-images-ic, from-images-is, from-images-od

• Added dataset writers that just output the images from datasets: to-images-ic, to-images-is, to-images-od

0.1.4 (2021-11-11)

• Added ISP for discarding polygons that either have too few or too many points (polygon-discarder)

• Added –verbose flag to dimension-discarder ISP for outputting information when an annotation gets discarded.

0.1.3 (2021-06-22)

• Added cross-domain converter which reduces object-detection datasets to image classification by looking for single/majority objects/labels.

0.1.2 (2021-06-01)

• Added void output formats for each domain which discard the conversion results.

• Added option to LocalFilenameSource which tells it to write the files it reads to a list-file.

0.1.1 (2021-05-20)

• Fixed build.

0.1.0 (2021-05-20)

• Initial release after separation from wai.annotations main repo.
