A boring Python + OpenCV example

OpenCV do not need to say more, first recommend a force tutorial:

Https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_tutorials.html

The example of tutorial is realized once, can have a basic understanding of OPENCV, but to do some practical things, still need to study deeply.

Today this article is very boring, just want to explain that the picture is essentially a three-dimensional array, using NumPy to create an array, with OPENCV display, the code is as follows.

ImportCv2ImportNumPy as Npimg3= Np.random.random ((600, 800, 3)) while1: Img3= Np.random.random ((600, 800, 3)) Img3*= 50IMG3=Img3.round () cv2.imshow ('img', IMG3)ifCv2.waitkey (1) & 0xff = = Ord ('Q'):         Breakcv2.destroyallwindows ()

This thing is fun, running out is a bunch of colored dots, like a TV without a signal.
