To get a sense for the total size of the labels in a dataset as a rule of Subsets of the samples you wish to annotate. Work into multiple smaller annotation runs that each contain limited If you are annotating very large scale video datasets with dense frame

Then, once the annotation work is complete, we merge the annotations back intoįiftyOne assumes that all labels in an annotation run can fit in memory. get_annotation_info ( anno_key )) # Step 4: Perform annotation in CVAT and save the tasks annotate ( anno_key, label_field = 'ground_truth', attributes =, launch_editor = True, ) print ( dataset. select ( sample_id ) # Step 3: Send samples to CVAT # A unique identifier for this run anno_key = 'cvat_basic_recipe' view. length (), reverse = True ) ) # Let's edit the ground truth annotations for the sample with the most # high confidence false positives sample_id = most_fp_view. filter_labels ( 'predictions', ( F ( 'confidence' ) > 0.8 ) & ( F ( 'eval' ) = 'fp' )). evaluate_detections ( 'predictions', gt_field = 'ground_truth', eval_key = 'eval' ) # Step 2: Locate a subset of your data requiring annotation # Create a view that contains only high confidence false positive model # predictions, with samples containing the most false positives first most_fp_view = ( dataset. load_zoo_dataset ( 'quickstart', dataset_name = 'cvat-annotation-example' ) dataset. Import fiftyone as fo import fiftyone.zoo as foz from fiftyone import ViewField as F # Step 1: Load your data into FiftyOne dataset = foz. Schemas, and download annotations using CVAT, all programmatically in Python.Īll of the following label types are supported, for both image and video To group multiple tasks together under a shared label schema.įiftyOne provides an API to create tasks and jobs, upload data, define label A task defines the label schema to use forĪnnotation and contains one or more jobs. A job contains one or more images and can be assigned to a That you can use to specify the necessary account credentials and serverĬVAT provides three levels of abstraction for annotation workflows: projects,

In either case, FiftyOne provides simple setup instructions You can use CVAT either through the demo server at To upload your data directly from FiftyOne to CVAT to add or edit labels. Open-source image and video annotation tools available, and we’ve made it easy
