WitrynaThe slowest run took 17.99 times longer than the fastest. This could mean that an intermediate result is being cached. 126 µs ± 218 µs per loop (mean ± std. dev. of 7 runs, 10 loops each) The slowest run took 574.21 times longer than the fastest. WitrynaJust like we normalize data points in machine learning as a pre-processing task, in the same way, we have to normalize pixels in the image for making images more appealing. To do so there is a function in OpenCV and it is cv2 normalize. In this entire tutorial, you will know how to normalize an image or picture and make it more appealing using the …
