Bitwise operations in opencv python
WebApr 4, 2024 · In 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 bitwise operators work only on integers. …
