Release the stored video after processing is done cap.release() The above function returns true if the video is successfully opened else returns false. To check if the video is successfully stored in the variable cap.isOpened()Ĭap is the variable that contains the video. Stores the video located in the given location to the variable. Reading a video from local storage cap = cv2.VideoCapture('LOCATION OF THE VIDEO') Stores live video from your webcam in the variable cap. Reading video directly from the webcam cap = cv2.VideoCapture(0)

The image is stored in the variable of type Mat that is in the form of a matrix. The above function stores the image in the file. Save an image to a file cv2.imwrite(filename, img) The above function shows the image stored in img variable. Showing the stored image cv2.imshow('image',img)

The above function converts the image to grayscale and then stores it in the variable img. The above function imread stores the image at the given location to the variable img.Ĭonverting an image to greyscale img = cv2.imread('watch.jpg',cv2.IMREAD_GRAYSCALE) Step 3:- Now simply import OpenCV in your python program in which you want to use image processing functions.Įxamples: Some basic functions of the OpenCV library (These functions are performed on Windows flavor of Anaconda but it will work on linux flavor too) Reading an image img = cv2.imread('LOCATION OF THE IMAGE') Step 2:- Type the given command, press enter, and let it download the whole package. Step 1:- After installing the anaconda open the Anaconda Prompt. Step 3:- Select Spyder as it is Anaconda’s IDE for python and OpenCV library will work in it only. Step 2:- Now you will see a menu with various options like Jupiter notebook, Spyder etc. Python program to convert a list to string.How to get column names in Pandas dataframe.Adding new column to existing DataFrame in Pandas.Top 40 Python Interview Questions & Answers.Perspective Transformation – Python OpenCV.
