WitrynaOpenCV is a library for image processing. We start this tutorial by opening a file and displaying it in a window. First we import the OpenCV library cv2 and give it the shortcut cv. import cv2 as cv Then we load an image from the current folder with the function cv.imread and display it with the function cv.imshow in a window called window. WitrynaThe imshow function produces a raster display of data associated with an np.ndarray or SpyFile object. In [1]: from spectral import * In [2]: img = open_image('92AV3C.lan') In [3]: view = imshow(img, (29, 19, 9)) When displaying the image interactively, the matplotlib button controls can be used to pan and zoom the displayed images.
