transform_random_perspective

Random perspective transformation of an image with a given probability


Description

Performs a random perspective transformation of the given image with a given probability

Usage

transform_random_perspective(
  img,
  distortion_scale = 0.5,
  p = 0.5,
  interpolation = 2,
  fill = 0
)

Arguments

img

A magick-image, array or torch_tensor.

distortion_scale

(float): argument to control the degree of distortion and ranges from 0 to 1. Default is 0.5.

p

(float): probability of the image being transformed. Default is 0.5.

interpolation

(int, optional) Desired interpolation. An integer 0 = nearest, 2 = bilinear, and 3 = bicubic or a name from magick::filter_types().

fill

(int or str or tuple): Pixel fill value for constant fill. Default is 0. If a tuple of length 3, it is used to fill R, G, B channels respectively. This value is only used when the padding_mode is constant. Only int value is supported for Tensors.
