這篇文章主要介紹了Python實現PS濾鏡中的USM銳化效果，幫助大家更好的利用python處理圖片，感興趣的朋友可以瞭解下

程式碼如下：import matplotlib.pyplot as plt

from skimage import io

from skimage.filters import gaussian

file_name='D:/Visual Effects/PS Algorithm/4.jpg';

img=io.imread(file_name)

img = img * 1.0

gauss_out = gaussian(img, sigma=5, multichannel=True)

# alpha 0 - 5

alpha = 1.5

img_out = (img - gauss_out) * alpha + img

img_out = out/255.0

# 飽和處理

mask_1 = out < 0

mask_2 = out > 1

img_out = out * (1-mask_1)

img_out = out * (1-mask_2) + mask_2

plt.figure()

plt.imshow(img/255.0)

plt.axis('off')

plt.figure(2)

plt.imshow(img_out)

plt.axis('off')

plt.show()

實現效果：
