transforms.RandomAdjustSharpness(sharpness_factor, p=0.5) sharpness_factor：需要调整多少锐度。可以是任何非负数 0-模糊，1-原图，2-锐度提高两倍

import torchvision.transforms as transform
from PIL import Image
import matplotlib.pyplot as plt
import numpy as np
import torch
img0=Image.open('lin-xiao-xun-000003.jpg')
img1=transform.RandomInvert(p=0.8)(img0)
axs = plt.figure().subplots(1,2)
axs[0].imshow(img0);axs[0].set_title('src');axs[0].axis('off')
axs[1].imshow(img1);axs[1].set_title('RandomInvert');axs[1].axis('off')

plt.show()
