Structural Similarity Index Measure (SSIM)¶

Module Interface¶

torchmetrics.StructuralSimilarityIndexMeasure[source]: alias of torchmetrics.image._deprecated._StructuralSimilarityIndexMeasure

Functional Interface¶

torchmetrics.functional.structural_similarity_index_measure(preds, target, gaussian_kernel=True, sigma=1.5, kernel_size=11, reduction='elementwise_mean', data_range=None, k1=0.01, k2=0.03, return_full_image=False, return_contrast_sensitivity=False)[source]

Wrapper for deprecated import.

>>> import torch
>>> preds = torch.rand([3, 3, 256, 256])
>>> target = preds * 0.75
>>> _structural_similarity_index_measure(preds, target)
tensor(0.9219)

Return type: Union[Tensor, Tuple[Tensor, Tensor]]
