Peak Signal-to-Noise Ratio (PSNR)¶

Module Interface¶

torchmetrics.PeakSignalNoiseRatio[source]: alias of torchmetrics.image._deprecated._PeakSignalNoiseRatio

Functional Interface¶

torchmetrics.functional.peak_signal_noise_ratio(preds, target, data_range=None, base=10.0, reduction='elementwise_mean', dim=None)[source]

Wrapper for deprecated import.

>>> from torch import tensor
>>> pred = tensor([[0.0, 1.0], [2.0, 3.0]])
>>> target = tensor([[3.0, 2.0], [1.0, 0.0]])
>>> _peak_signal_noise_ratio(pred, target)
tensor(2.5527)

Return type: Tensor
