图像的输入/输出操作

import cv2 # 导入OpenCV库

image = cv2.imread("./images/hens/paprika2.jpg") # 从文件路径读取图像 type_of_image = type(image) # 查看该对象的类型 image_shape = image.shape # 图像的形状（高度H，宽度W，通道数C）

print(f"type_of_image = {type_of_image}; image_shape = {image_shape}")

import cv2 # 导入OpenCV库 import os

image = cv2.imread("./images/hens/paprika2.jpg") # 从文件路径读取图像 cv2.imwrite(os.path.join('./output', 'the_mysterious_image.png'), image) # 将图像写入文件

cv2.imshow("Paprika", image) cv2.waitKey(0)
