【python】 图像增强相关操作

亮度，对比度，色度，锐度

from PIL import Image
from PIL import ImageEnhance

img = Image.open(r"4044920.jpg")

# 提高亮度
enh_bri = ImageEnhance.Brightness(img)
# brightness = np.random.uniform(0.5,2,)
brightness = 0.85
print(brightness)
image_brightened = enh_bri.enhance(brightness)
image_brightened.show()

# 提高色度
enh_col = ImageEnhance.Color(img)
color = np.random.uniform(0.5, 1.4,)
image_colored = enh_col.enhance(color)
image_colored.show()

# 饱和度

# 对比度
enh_con = ImageEnhance.Contrast(img)
constrast = np.random.uniform(0.5, 1.1)
image_constrast = enh_con.enhance(constrast)
image_constrast.show()

# 灰度系数

# 锐度
enh_sha = ImageEnhance.Sharpness(img)
sharpness = np.random.uniform(0.5, 2)
# print(sharpness)
image_sharped = enh_sha.enhance(sharpness)
image_sharped.show()
