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.

Mean Filter - The mean filter is employed to blur an image to get rid of the noise. This filter calculates the mean of pixel values in a kernel or mask considered. To remove some of the noise, the pixel value of the center element is replaced with mean. We can use the inbuilt function in Opencv to apply this filter By Ahin Subhra Das. Image Processing is most commonly termed as 'Digital Image Processing' and It is considered as a subset of Computer Vision. Both Image Processing algorithms and Computer Vision (CV) algorithms take an image as input; however, in image processing, the output is also an image, whereas in computer vision the output can be some features/information about the image
