试题六（15 分）阅读下列说明，回答问题 1 至问题3，将解答填入答题纸的对应栏内。【说明】当把一只小鸭图片（图A）放到一张背景图（图B）上时，背景图将被小鸭图片遮住一个矩形区域（图C）。利用程序设计语言处理图形图像数据，可以使图片上非小鸭的其他部分变成透明，使观察者不会感觉到小鸭图片遮住一个矩形区域。在编程之前，使用图像处理工具软件对小鸭图片进行处理。首先将原始的小鸭图片复制两份，其中一幅图片将其应该透明之处（小鸭的背景）设置为黑色（图D），另一幅图片将其非透明之处设置为黑色，其余地方（小鸭的背景）设置为白色（图E）。
【问题 2】（6 分）（1）图像处理中，灰度图像A 和B 能否直接进行逻辑运算？（2）图像处理中，灰度图像A 和B 能否直接进行算术运算？（3）请写出3 种最基本的用于图像处理的算术运算。
参考答案：（1） 不能进行逻辑运算。（2） 可以进行算术运算。（3） 最基本的用于图像处理的算术运算包括加法、减法、乘法、除法。
