autocontrast(img: torch.Tensor) → torch.Tensor¶
Maximize contrast of an image by remapping its pixels per channel so that the lowest becomes black and the lightest becomes white.
img (PIL Image or Tensor) – Image on which autocontrast is applied. If img is torch Tensor, it is expected to be in […, 1 or 3, H, W] format, where … means it can have an arbitrary number of leading dimensions. If img is PIL Image, it is expected to be in mode “L” or “RGB”.
An image that was autocontrasted.
