Sets each bit to 1 if only one of two bits is 1 ~ NOT Inverts all the bits << Zero fill left shift Shift left by pushing zeros in from the right and let the leftmost bits fall off >> Signed right shift Shift right by pushing copies of the leftmost bit in from the left, and ...
六、形态图像处理 在本章中,我们将讨论数学形态学和形态学图像处理。形态图像处理是与图像中特征的形状或形态相关的非线性操作的集合。这些操作特别适合于二值图像的处理(其中像素表示为 0 或 1,并且根据惯例,对象的前景=1 或白色,背景=0 或黑色),尽管它可以扩展到灰度图像。 在形态学运算中,使用结构元素(小模...

Apply a function of two arguments cumulatively to the items of a sequence, from left to right, so as to reduce the sequence to a single value. For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates (((1+2)+3)+4)+5). If initial is present, it is placed bef...

In this script, we're going to set the bits from left to right using binary bit shifting in the range defined by our CIDR. We use a for loop to iterate through this range and do the math. That math, in words, is: Take the mod of the current iterator and eight. Subtract it from...
# zero fill left shift (<<)# zeros are filled from right, bits are shifted to left# left most bits fall off# in this example, we shift the bits of b twice# 10 (b) shifted twice is 1000 (which is decimal 8)print(b << 2) ...
Geek Bits Python uses the name “function” to describe a reusable chunk of code. Other programming languages use names such as “procedure,”“subroutine,” and “method.” When a function is part of a Python class, it‘s known as a “method.”. You’ll learn all about Python’s clas...
