Duplicates

class dataeval.detectors.linters.Duplicates(only_exact: bool = False)

Finds the duplicate images in a dataset using xxhash for exact duplicates and pchash for near duplicates

stats

Output class of stats

Type:

StatsOutput

Parameters:

only_exact (bool, default False) – Only inspect the dataset for exact image matches

Example

Initialize the Duplicates class:

>>> dups = Duplicates()

evaluate(data: Iterable[_SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | bool | int | float | complex | str | bytes | _NestedSequence[bool | int | float | complex | str | bytes]] | StatsOutput | Sequence[StatsOutput]) → DuplicatesOutput

Returns duplicate image indices for both exact matches and near matches

Parameters:

data (Iterable[ArrayLike], shape - (N, C, H, W) | StatsOutput | Sequence[StatsOutput]) – A dataset of images in an ArrayLike format or the output(s) from an imagestats metric analysis

Returns:

List of groups of indices that are exact and near matches

Return type:

DuplicatesOutput

>>> dups.evaluate(images)
DuplicatesOutput(exact=[[3, 20], [16, 37]], near=[[3, 20, 22], [12, 18], [13, 36], [14, 31], [17, 27], [19, 38, 47]])
