你用 Python 写过哪些有趣的脚本？

# 图片格式转换, Jpg转Png # 方法① from PIL import Image img = Image.open('test.jpg') img.save('test1.png') # 方法② from cv2 import imread, imwrite image = imread("test.jpg", 1) imwrite("test2.png", image)

# 图像转换 import cv2 # 读取图片 img = cv2.imread("img.jpg") # 灰度 grey = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) invert = cv2.bitwise_not(grey) # 高斯滤波 blur_img = cv2.GaussianBlur(invert, (7, 7), 0) inverse_blur = cv2.bitwise_not(blur_img) sketch_img = cv2.divide(grey, inverse_blur, scale=256.0) # 保存 cv2.imwrite('sketch.jpg', sketch_img) cv2.waitKey(0) cv2.destroyAllWindows()
