Arithmetic Operations on Images - OpenCV
I want to put the OpenCV logo above an image. If I add two images, it will change the color. If I blend them, I get a transparent effect. But I want it to be opaque. If it was a rectangular region, I could use ROI as we did in the last chapter. But the OpenCV logo is a not a rectangular shape. So you can do it with bitwise operations as shown ...

Bit Manipulation Hacks | Brilliant Math & Science Wiki
In this wiki, we shall discuss a number of one liners that help us solve simple arithmetic problems in binary numbers. They are often found to be very useful (and quick) in larger programs. Because of the way numbers are represented in computers, these one liners are not only handy for the programmer but also very fast in execution. The Bitwise operators constitute the standard operators from ...

python - What does a star (asterisk) do in f-string? - Stack Overflow
Note that using or_expr as the operand to * does not mean that a bitwise or-operator has to be used there - it just means that the bitwise or-operator is the first operator in the precedence-hierachy that would be allowed as an operand to *. So it's just about setting the precedence of prefix * vs. other expressions.

Python Operators: The Complete Guide – TheLinuxCode
In Python, integers are represented using two‘s complement, which affects how the bitwise NOT operator works: a = 10 print(~a) # -11 # This is because ~a is equivalent to -(a+1) print(-(a+1)) # -11 Practical Applications of Bitwise Operators. Flag manipulation: Using bits to represent multiple boolean flags efficiently
