【python下使用OpenCV实现计算机视觉读书笔记2】图像与字节的变换

import cv2

import 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(‘RandomColor.png‘, bgrImage)
