WebOct 9, 2024 · TL;DR the area mode of torch.nn.functional.interpolate is probably one of the most intuitive ways to think of when one wants to downsample an image. You can think of it as applying an averaging Low-Pass Filter (LPF) to the original image and then sampling. Applying an LPF before sampling is to prevent potential aliasing in the downsampled image. http://pytorch.org/vision/main/generated/torchvision.transforms.functional.resize.html do married couples need an lpa
