In mlverse/torchvision: Models, Datasets and Transformations for Images

Randomly selects a rectangular region in an image and erases its pixel values

Description

'Random Erasing Data Augmentation' by Zhong et al. See https://arxiv.org/pdf/1708.04896

Usage

transform_random_erasing(
  img,
  p = 0.5,
  scale = c(0.02, 0.33),
  ratio = c(0.3, 3.3),
  value = 0,
  inplace = FALSE
)

Arguments

img	A magick-image, array or torch_tensor.
p	probability that the random erasing operation will be performed.
scale	range of proportion of erased area against input image.
ratio	range of aspect ratio of erased area.
value	erasing value. Default is 0. If a single int, it is used to erase all pixels. If a tuple of length 3, it is used to erase R, G, B channels respectively. If a str of 'random', erasing each pixel with random values.
inplace	boolean to make this transform inplace. Default set to FALSE.
