通过OpenCV将随机数转换成图片 Python实现

import cv2import numpyimport os# Make an array of 120,000 random bytes.randomByteArray = bytearray(os.urandom(120000))flatNumpyArray = numpy.array(randomByteArray)#Convert the array to make a 400x300 grayscale image.grayImage = flatNumpyArray.reshape(300, 400)cv2.imwrite('RandomGray.png', grayImage)#Convert the array to make a 400x100 color image.bgrImage = flatNumpyArray.reshape(100, 400, 3)cv2.imwrite('RandonColor.png', bgrImage)
