Image processing using OpenCV python

Install OpenCV by using pip install OpenCV-python command. To import the cv2 model use import cv2 command. Now lets discuss some more command we used in task: img = cv2.imread (pyimg.jpg) = To read the image, use the imread () method of the cv2 module. cv2.imshow ('Original Image', img) =To display the image, you can use the imshow. That why image processing using OpenCV is so easy. All the time you are working with a NumPy array. To display the image, you can use the imshow() method of cv2. cv2.imshow('Original Image', img) cv2.waitKey(0) The waitkey functions take time as an argument in milliseconds as a delay for the window to close Image Processing Using OpenCV and Python. What is Image Processing? Image processing is any form of processing for which the input is an image or a series of images or videos, such as photographs or frames of video.The output of image processing can be either an image or a set of characteristics or parameters related to the image. Open-CV.
