torchvision.transforms.functional.resized_crop(img: Tensor, top: int, left: int, height: int, width: int, size: List[int], interpolation: InterpolationMode = InterpolationMode.BILINEAR, antialias: Optional[bool] = True) Tensor[source]

Crop the given image and resize it to desired size. If the image is torch Tensor, it is expected to have […, H, W] shape, where … means an arbitrary number of leading dimensions

Notably used in RandomResizedCrop.

  • img (PIL Image or Tensor) – Image to be cropped. (0,0) denotes the top left corner of the image.

  • top (int) – Vertical component of the top left corner of the crop box.

  • left (int) – Horizontal component of the top left corner of the crop box.

  • height (int) – Height of the crop box.

  • width (int) – Width of the crop box.

  • size (sequence or int) – Desired output size. Same semantics as resize.

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

  • antialias (bool, optional) –

    Whether to apply antialiasing. It only affects tensors with bilinear or bicubic modes and it is ignored otherwise: on PIL images, antialiasing is always applied on bilinear or bicubic modes; on other modes (for PIL images and tensors), antialiasing makes no sense and this parameter is ignored. Possible values are:

    • True (default): will apply antialiasing for bilinear or bicubic modes. Other mode aren’t affected. This is probably what you want to use.

    • False: will not apply antialiasing for tensors on any mode. PIL images are still antialiased on bilinear or bicubic modes, because PIL doesn’t support no antialias.

    • None: equivalent to False for tensors and True for PIL images. This value exists for legacy reasons and you probably don’t want to use it unless you really know what you are doing.

    The default value changed from None to True in v0.17, for the PIL and Tensor backends to be consistent.
