adjust_brightness¶
- torchvision.transforms.functional.adjust_brightness(img: Tensor, brightness_factor: float) Tensor[source]¶
Adjust brightness 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.
brightness_factor (float) – How much to adjust the brightness. Can be any non-negative number. 0 gives a black image, 1 gives the original image while 2 increases the brightness by a factor of 2.
- Returns:
Brightness adjusted image.
- Return type:
