cv2.IMREAD_REDUCED_COLOR_4：如果设置，总是将图像转换为3通道BGR彩色图像，图像尺寸减小1/4。
cv2.IMREAD_REDUCED_GRAYSCALE_8：如果设置，总是将图像转换为单通道灰度图像，图像尺寸减小1/8。
cv2.IMREAD_REDUCED_COLOR_8：如果设置，总是将图像转换为3通道BGR彩色图像，图像尺寸减小1/8
常用的是前三种。因为flags是整型，所以传入数值也行：
flags >0：等同于IMREAD_COLOR。
flags =0：等同于 IMREAD_GRAYSCALE。
flags <0： 等同于IMREAD_UNCHANGED。
通常是给1、0、-1，给其他整型也是可以的。

cv2.imShow():
函数可以在窗口中显示图像。该窗口和图像的原始大小自适应
cv2.waitKey():
cv2.waitKey() 是一个键盘绑定函数。需要指出的是它的时间尺度是毫秒级。
函数等待特定的几毫秒，看是否有键盘输入。特定的几毫秒之内，如果
按下任意键，这个函数会返回按键的 ASCII 码值，程序将会继续运行。如果没
有键盘输入，返回值为 -1，如果我们设置这个函数的参数为 0，那它将会无限
期的等待键盘输入。我们也可以将其设置为一个特定的键。
cv2.destroyALLWindows():
销毁我们创建的所有窗口。
如果要销毁任何特定窗口，请使用函数cv2.destroyWindow()，其中传递确切的窗口名称作为参数。
(应该是使用创建窗口时所使用的窗口名称，字符串类型。)
注：
我们还可以使用另一种方法来加载图片：先创建一个窗口，之后在需要的时候将图像加载到该窗口。
说明：在这种情况下，用cv2.namedWindow()函数可以指定窗口是否可以调整大小。
