Module Interface¶

torchmetrics.MultiScaleStructuralSimilarityIndexMeasure[source]: alias of torchmetrics.image._deprecated._MultiScaleStructuralSimilarityIndexMeasure

Functional Interface¶

torchmetrics.functional.multiscale_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, betas=(0.0448, 0.2856, 0.3001, 0.2363, 0.1333), normalize='relu')[source]

Wrapper for deprecated import.

>>> import torch
>>> preds = torch.rand([3, 3, 256, 256], generator=torch.manual_seed(42))
>>> target = preds * 0.75
>>> _multiscale_structural_similarity_index_measure(preds, target, data_range=1.0)
