class surfify.nn.modules.IcoSpMaConvTranspose(in_feats, out_feats, kernel_size, stride=1, pad=0, zero_pad=0, output_shape=None)[source]¶

Define the transpose convolution on icosahedron discretized sphere using spherical 2-d mapping & circular padding.

Notes

Debuging messages can be displayed by changing the log level using setup_logging(level='debug').

Examples

>>> import torch
>>> from surfify.nn import IcoSpMaConvTranspose
>>> module = IcoSpMaConvTranspose(
        in_feats=16, out_feats=8, kernel_size=4, stride=2, zero_pad=3,
        pad=1)
>>> proj_ico_x = torch.zeros((10, 16, 96, 96))
>>> proj_ico_x = module(proj_ico_x)
>>> proj_ico_x.shape

Init IcoSpMaConvTranspose.

Parameters:

in_feats : int

input features/channels.

out_feats : int

output features/channels.

kernel_size : int or tuple

the convolutional kernel size.

stride : int or tuple, default 1

controls the stride for the cross-correlation.

pad : int or tuple (pad_azimuth, pad_elevation), default 0

the size of the padding.

zero_pad : int or tuple, default 0

add a zero padding in both axes before the transpose convolution.

forward(x)[source]¶

Define the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
