WebThe grid generator generates a grid of coordinates in the input image corresponding to each pixel from the output image. The sampler uses the parameters of the transformation and applies it to the input image. Note We need the latest version of PyTorch that contains affine_grid and grid_sample modules. WebMay 3, 2024 · When align_corners = True, the grid positions depend on the pixel size relative to the input image size, and so the locations sampled by grid_sample () will differ for the same input given at different resolutions (that is, after being upsampled or downsampled). The default behavior up to version 1.2.0 was align_corners = True.
