Shape ) to display the dimensions of our source image. Henceforth, we will use the image above in this paper. Let’s first try reading our image source and displaying it with the functions previously described. As explained earlier in this article, we will learn how to apply resizing, cropping, and rotating techniques to images. Now we can go back to the original topic of basic image manipulation in OpenCV and Python. import cv2įor details on OpenCV Core Image Operations, please read the OpenCV documentation. To write / save images in OpenCV using a function cv2.imwrite()where the first parameter is the name of the new file that we will save and the second parameter is the source of the image itself. import cv2Ĭv2.imshow('Displaying Images', img) Writing / Saving Images Displaying an Imageĭisplaying an image in OpenCV using a function cv2.imshow()where the first parameter is the window name to display the image and the second parameter is the image itself.
destroyAllWindows ( ) is to close other windows that are currently open. Whiskey ( 0 ) is to keep the window displaying the image. To read images in OpenCV, use a function cv2.imread()where the first parameter is the image file name complete with its extension.
