WebJan 6, 2024 · PyTorch Server Side Programming Programming To pad an image on all sides, we can apply Pad () transform provided by the torchvision.transforms module. This module contains many important transformations that can be used to perform different types of manipulations on the image data. WebApply affine transformations that differ between local neighbourhoods. This augmentation places a regular grid of points on an image and randomly moves the neighbourhood of these point around via affine transformations. This leads to local distortions. This is mostly a wrapper around scikit-image's PiecewiseAffine .

WebApr 10, 2024 · For a large dataset (~25, 000 images), it will take an extra ~1.4h to process images per epoch, which heavily increase the whole training time. Thus, I wonder if it can be accelerated if it can be processed on GPU. But I can only find some random affine transformations in torchvision.transforms.RandomAffine. WebSome of the available functionalities which are worth to mention are the following: random rotations; affine and perspective transformations; several random color intensities transformations, image noise distortion, motion blurring, and many of the different differentiable data augmentation policies.
