OpenCV: Arithmetic Operations on Images
Bitwise Operations. This includes the bitwise AND, OR, NOT, and XOR operations. They will be highly useful while extracting any part of the image (as we will see in coming chapters), defining and working with non-rectangular ROI's, and etc. Below we will see an example of how to change a particular region of an image.

Python Bitwise Operators - Intellipaat
Python uses 2’s complement representation for negative integers, which explains the behavior of bitwise NOT and right shift operations with negative numbers. You also learned how bitwise shift operators can be used for efficient multiplication and division by powers of 2.

hex() function in Python - GeeksforGeeks
Explanation: ord('a') converts the character 'a' to its ASCII value, which is 97. hex(ord('a')) converts the ASCII value 97 into its hexadecimal equivalent 0x61. float.hex(3.9) converts the floating-point number 3.9 into its hexadecimal representation 0x1.f333333333333p+1. Example 2: In this example, we perform bitwise AND and bitwise OR operations on two hexadecimal numbers a and b.

Sum of Two Integers without using "+" operator in python
Recall that bitwise xor is 1 when the bits differ, and 0 when the bits are the same. For example (where D is decimal and B is binary), 20D == 10100B, and 9D = 1001B: 10100 1001 ----- 11101 and 11101B == 29D. But, if you have a case with a carry, it doesn't work so well. For example, consider adding (bitwise xor) 20D and 20D. 10100 10100 ----- 00000

Python XOR Operator (^) Explained with Examples - TechBeamers
This bitwise operation works because XORing a number with itself results in 0. # Swapping variables using XOR x = 10 y = 20 x ^= y y ^= x x ^= y print(x) ... It’s important to note the difference between bitwise XOR and logical XOR in Python. While bitwise XOR operates at the bit level, logical XOR operates on Boolean values, ...

Rotate bits of a number - GeeksforGeeks
Python bitwise operators are used to perform bitwise calculations on integers. The integers are first converted into binary and then operations are performed on each bit or corresponding pair of bits, hence the name bitwise operators. The result is then returned in decimal format.Note: Python bitwis

3 Python: Input/Output, Operators, Data Types, Strings, List
5) Bitwise Operators. Bitwise operators act on operands bit by bit, treating them as sequences of binary digits, and most bitwise operators demand two operands since they are binary in nature. The bitwise NOT operator (~) is the sole unary operator because it only demands a single operand, which must always be at the right side of the statement.

Understanding OpenCV: Your Guide to Image Processing in Python | Course ...
Bitwise AND operator: Sets each bit to 1 if both bits are 1. Here's the basic syntax for using cv.bitwise_and() in Python: result = cv.bitwise_and(Image 1, Image 2, mask) In this syntax: • Image 1 and Image 2 are the input images or arrays on which you want to perform the bitwise AND operation.
