Arithmetic Operations on Images - OpenCV
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 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

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 ...

BCD or Binary Coded Decimal - GeeksforGeeks
3. Slower Processing Speed: Due to the need for additional correction and conversion steps, BCD operations take longer than binary operations, affecting processing speed. 4. Limited Range: BCD can represent only decimal digits (0-9). It cannot handle fractional values efficiently without additional complexity, limiting its versatility in ...

Practice With Arithmetic Operators | Saylor Academy
2. Operators. An operator is a symbol or function that indicates an operation.For example, in math the plus sign or + is the operator that indicates addition. In Python, we will see some familiar operators that are brought over from math, but other operators we will use are specific to computer programming.
