perspective

torchvision.transforms.functional.perspective(img: Tensor, startpoints: List[List[int]], endpoints: List[List[int]], interpolation: InterpolationMode = InterpolationMode.BILINEAR, fill: Optional[List[float]] = None) Tensor[source]

Perform perspective transform of the given image. If the image is torch Tensor, it is expected to have […, H, W] shape, where … means an arbitrary number of leading dimensions.

Parameters:
  • img (PIL Image or Tensor) – Image to be transformed.

  • startpoints (list of list of python: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 python: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 (InterpolationMode) – Desired interpolation enum defined by torchvision.transforms.InterpolationMode. Default is InterpolationMode.BILINEAR. If input is Tensor, only InterpolationMode.NEAREST, InterpolationMode.BILINEAR are supported. The corresponding Pillow integer constants, e.g. PIL.Image.BILINEAR are accepted as well.

  • fill (sequence or number, optional) –

    Pixel fill value for the area outside the transformed image. If given a number, the value is used for all bands respectively.

    Note

    In torchscript mode single int/float value is not supported, please use a sequence of length 1: [value, ].

Returns:

transformed Image.

Return type:

PIL Image or Tensor
