Python OpenCV | cv2.imshow()方法介绍 _OpenCVcv2.imshow

OpenCV的Python
是旨在解决计算机视觉问题的Python绑定库。 cv2.imshow()方法用于在窗口中显示图像。窗口自动适合图像尺寸。

语法：cv2.imshow(window_name, image)参数：window_name：字符串, 表示要在其中显示图像的窗口的名称。图像：这是要显示的图像。返回值：不返回任何内容。

用于以下所有示例的图像：

示例1：

# Python program to explain cv2.imshow() method # importing cv2 import cv2 # path path = r 'C:\Users\Rajnish\Desktop\srcmini.png'# Reading an image in default mode image = cv2.imread(path)# Window name in which image is displayed window_name = 'image'# Using cv2.imshow() method # Displaying the image cv2.imshow(window_name, image)#waits for user to press any key #(this is necessary to avoid Python kernel form crashing) cv2.waitKey( 0 ) #closing all open windows cv2.destroyAllWindows()

输出如下：

示例2：

# Python program to explain cv2.imshow() method# importing cv2 import cv2# path path = r 'C:\Users\Rajnish\Desktop\srcmini.png'# Reading an image in grayscale mode image = cv2.imread(path, 0 )# Window name in which image is displayed window_name = 'image'# Using cv2.imshow() method # Displaying the image cv2.imshow(window_name, image)# waits for user to press any key # (this is necessary to avoid Python kernel form crashing) cv2.waitKey( 0 )# closing all open windows cv2.destroyAllWindows()
