superannotate.benchmark(gt_project_name, project_names, export_root=None, image_list=None, annot_type='bbox', show_plots=False)

Computes benchmark score for each instance of given images that are present both gt_project_name project and projects in project_names list:

Parameters:
  • gt_project_name (str) – Project name that contains the ground truth annotations
  • project_names (list of str) – list of project names to aggregate through
  • export_root (Pathlike (str or Path)) – root export path of the projects
  • image_list (list) – List of image names from the projects list that must be used. If None, then all images from the projects list will be used. Default: None
  • annot_type (str) – Type of annotation instances to consider. Available candidates are: [“bbox”, “polygon”, “point”]
  • show_plots (bool) – If True, show plots based on results of consensus computation. Default: False
