torchvision.transforms.functional.adjust_sharpness(img: Tensor, sharpness_factor: float) → Tensor[source]¶

Adjust the sharpness of an image.

Parameters:

• img (PIL Image or Tensor) – Image to be adjusted. 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.
• sharpness_factor (float) – How much to adjust the sharpness. Can be any non-negative number. 0 gives a blurred image, 1 gives the original image while 2 increases the sharpness by a factor of 2.

Returns:
