ObjectDetectionAveragePrecision

class ObjectDetectionAveragePrecision

Calculate average precision and recall for object detection.

Parameters

max_dets: Union[List[int], Tuple[int]], default: [1, 10, 100]

Maximum number of detections per class.

area_range: tuple, default: (32**2, 96**2)

Slices for small/medium/large buckets.

return_option: str, default: ‘ap’

ap: ap only, ar: ar only, None: all (not ignite complient)

__init__(*args, max_dets: Union[List[int], Tuple[int]] = (1, 10, 100), area_range: Tuple = (1024, 9216), return_option: Optional[str] = 'ap', average: str = 'none', iou_range: Tuple[float, float, float] = (0.5, 0.95, 10), **kwargs)

__new__(*args, **kwargs)
