annotation_overview:
name: annotation_overview
description: Short descriptive summary indicating the type of annotation and how
it was generated
examples:
- value: Segmentation masks of human cell nuclei curated by experts from a model
prediction
- value: Manual quantification of the number of cells in mouse embryos performed
by experts

annotation_method:
name: annotation_method
description: Description of how the annotations were created. For example, were
the annotations crowdsourced or expertly annotated, produced by a human or
software, what software was used, when were the annotations created, protocols
used for consensus and quality assurance
examples:
- value: A machine learning-based framework was utilized to produce a first coarse
annotation of nuclear contours. Then, a disease expert curated all annotations
by editing, adding, or removing polygons. Finally, an expert pathologist
revised all image annotations and a final version of the annotations was curated.
- value: Cell counts were performed manually by expert biologists. For cases difficult
to quantify, a vote including all experts was taken and annotations were
corrected according to the majority view.

annotation_criteria:
name: annotation_criteria
description: Rules used to generate annotations
examples:
- value: Only nuclei in focus were annotated, if parts of a nucleus were out of
focus, only the part of the nucleus being in focus was annotated
- value: During cell counting, cell division was tracked using anillin localization.
Mitosis was considered completed when anillin stop localising at the contractile
ring and re-entered the cell nucleus, at which point the dividing cell was
considered two different cells.

annotation_coverage:
name: annotation_coverage
description: Which images from the dataset were annotated, and what percentage
of the data has been annotated from what is available
examples:
- value: All images were annotated
- value: 'Images: image_1, image_2 and image_3 were not annotated due to the abnormal
cell death rates compared to other samples.'

annotation_confidence_level:
name: annotation_confidence_level
description: Confidence on annotation accuracy
examples:
- value: Curators had 15 and 20 years of experience working in cancer pathology
- value: To characterize the quality of gold standard segmentation annotations, we
calculated the average and standard deviation performance of the three independent
annotators relative to the gold truth that was established by merging the
triplets of manual annotations. For the whole dataset this metric was 0.904±0.081
