Randomly selects a rectangular region in an image and erases its pixel values — transform_random_erasing • torchvision

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

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.
