WebExample 1: Resize Image – cv2.resize () In the following example, we are going to see how we can resize the above image using cv2. resize () while preserving the aspect ratio. We will resize the image to 50% of its actual shape, i.e., we will reduce its height to 50% of its original and width to 50% of its original. WebIt passes the number of dimensions =1 to the Mat constructor but the created array will be 2-dimensional with the number of columns set to 1. So, Mat::dims is always >= 2 (can also be 0 when the array is empty). Use a copy constructor or assignment operator where there can be an array or expression on the right side (see below).
