用absdiff()计算了2幅图像差异后得到的新图像,再用countNonZero()计算这个新图像中非0的像素点个数,可以比较出2幅图像的差异,OpenCV-Python教程:形态学变换~开闭操作,顶帽黑帽,形态学梯度,击中击不中(morphologyEx)中比较开操作和先腐蚀后膨胀图像差异时有具体的例子。

for num in range(1, 4): sum *= num print(sum) 1. 2. 3. A. TypeError出错 B. 6 C. 7 D. 7.0 这段代码会报错,因为sum变量没有被定义和没有初始值,Python解释器无法识别sum的数据类型。在for循环前加一行赋值语句: sum = 1 就正常了。
