adjust_brightness¶
- torchvision.transforms.functional.adjust_brightness(img: Tensor, brightness_factor: float) Tensor[源码]¶
调整图像亮度。
- 参数:
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) – 调整亮度的程度。可以是任何非负数。0 会得到一张黑色图像，1 会得到原始图像，而 2 会将亮度提高一倍。
- 返回:
亮度调整后的图像。
- 返回类型:
PIL 图像或张量
