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.

The Bitwise operators constitute the standard operators from boolean algebra along with the shift operators. Bitwise AND (&) Apply AND bit by bit on the operand integers. Bitwise OR ... Operation: Code: Example: Turn off the rightmost 1-bit: turnOff = lambda x: x & (x-1) 01011000 \(\to\) 01010000: Turn on the rightmost 0-bit:

Python Operators: The Complete Guide – TheLinuxCode

Division in Python 2 vs Python 3. One important distinction to note is how division works across Python versions: In Python 2, the / operator performed floor division between integers (returning an integer); In Python 3, the / operator always performs true division (returning a float); The // operator performs floor division in both versions ...

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.

Bitwise XOR of All Pairings - docs.vultr.com

The problem involves computing the Bitwise XOR for all pairings between two sets of integers. In Python, given two lists set1 and set2, calculate this combined XOR based on certain conditions. Initialize two integers xor_result1 and xor_result2 to zero, which will store the interim XOR results of elements from set1 and set2 respectively.

Practice With Arithmetic Operators | Saylor Academy

In Python 2 the quotient returned for the expression 11 / 2 is 5. Python 2's / operator performs floor division, where for the quotient x the number returned is the largest integer less than or equal to x. If you run the above example of print (80 / 5) with Python 2 instead of Python 3, you'll receive 16 as the output without the decimal place.
