This issue is meant to be a place for brainstorming about various metrics which will then be implemented in btk.metrics.

  • low-level metrics:

    • detection: detection of a blend, detection of the correct number of objects in a blend, accuracy of the position of the centers of objects
    • segmentation: quality of the masks
    • deblending: pixel-wise comparison, blendedness (as defined in the Scarlet paper)

  • high-level metrics involving measurements:

    • flux/colors
    • photo-z: bias
    • size and shape
    • shear:
      • selection effects
      • exclusion bias
      • impact on shear estimators
