transform_perspective: Perspective transformation of an image

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

Perspective transformation of an image

Description

Perspective transformation of an image

Usage

transform_perspective(
  img,
  startpoints,
  endpoints,
  interpolation = 2,
  fill = NULL
)

Arguments

img	A magick-image, array or torch_tensor.
startpoints	(list of list of ints): List containing four lists of two integers corresponding to four corners ⁠[top-left, top-right, bottom-right, bottom-left]⁠ of the original image.
endpoints	(list of list of ints): List containing four lists of two integers corresponding to four corners ⁠[top-left, top-right, bottom-right, bottom-left]⁠ of the transformed image.
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.
