    # 读取图片
    im = Image.open(r"F:\artificial_inligence\DL\liev_CD"
                    r"\project2\yolo2-pytorch-master\demo\horses.jpg")

    im = im.convert("L")  # 转为灰度图
    data = im.getdata()
    print(data)
    data = np.matrix(data)
    print(data)
    #     print data
    # 变换成512*512
    data = np.reshape(data, (512, 773))
    new_im = Image.fromarray(data)
    # 显示图片
    new_im.show()
