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 - What does a star (asterisk) do in f-string ... - Stack Overflow

In the python document 2.4.3. Formatted string literals, it seems possible to write a star followed by an expression in a f-string's {}, but I cannot find how to use that. ... @Kasrâmvd Note that using or_expr does not mean that an or-operator has to be used there - it just means that the bitwise or operator is the first operator in the ...

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.

BCD or Binary Coded Decimal - GeeksforGeeks

Embedded systems rely on BCD for fast and efficient decimal operations. Working of Binary Coded Decimal. In BCD, each decimal digit (0-9) is converted into its 4-bit binary equivalent. For example: Decimal 0 is represented as 0000 in BCD. Decimal 1 is represented as 0001 in BCD. Decimal 2 is represented as 0010 in BCD and so on.

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 # Python 3 print(7 / 2) # Output: 3.5 print(7 // 2 ...

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.
