Resizing With Different Interpolation Methods WitrynaIn OpenCV, you display an image using the imshow () function. Here’s the syntax: imshow (window_name, image) This function also takes two arguments: The first argument is the window name that will be displayed on the window. The second argument is the image that you want to display.
