meddlr.modeling.layers.GaussianBlur#

class meddlr.modeling.layers.GaussianBlur(kernel_size: Union[int, Tuple[int, ...]], sigma: Union[float, Tuple[float, ...]])[source]#

Creates an operator that blurs a tensor using a Gaussian filter.

The operator smooths the given tensor with a gaussian kernel by convolving it to each channel. It suports batched operation.

Parameters

kernel_size (Tuple[int, int]) – the size of the kernel. Dimensions are ([D, H], W)
sigma (Tuple[float, float]) – the standard deviation of the kernel. Dimensions are ([D, H], W)

Returns

the blurred tensor. Shape \((B, C, [..., H], W)\)

Return type

Tensor

Shape:

Input: \((B, C, H, W)\)
Output: \((B, C, H, W)\)

Examples

>>> input = torch.rand(2, 4, 5, 5)
>>> gauss = GaussianBlur((3, 3), (1.5, 1.5))
>>> output = gauss(input)  # 2x4x5x5
