WebNov 27, 2024 · Bitwise Operator in C/C++ In C++, there are a total of six bitwise operators. The six bitwise operators are bitwise AND (&), bitwise OR ( ), bitwise XOR (^), left shift (<<), right shift (>>), and bitwise NOT (~). The & (bitwise AND) in C++ takes two numbers as operands and does AND on every bit of two numbers. WebJul 20, 2016 · Moreover, bitwise_not is not exactly a not operator, but in the case of boolean matrix in OpenCV, it acts the same, since bool Mat are uint8_t and false has a value of 0 (0b00000000) and true has a value of 255 (0b11111111), making bitwise_not acting exactly the same as simple not. – Cedric Jul 20, 2016 at 2:01 Add a comment … mediacorp wondershop
