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

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