WebOne source of your problems could be you do not check inBuffer for NULL values before you use it. If no descriptors were generated from the image you pass in, desc.data, and by extension inBuffer, will be NULL. A few more things: Your use of reinterpret_cast is unnecessary, and quite possibly unsafe. See this question for a good explanation of cast … 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 … WebThe bitwise NOT, or bitwise complement, is a unary operation that performs logical negation on each bit, forming the ones' complement of the given binary value. Bits that are 0 become 1, and those that are 1 become 0. For example: NOT 0111 (decimal 7) = 1000 (decimal 8) NOT 10101011 (decimal 171) = 01010100 (decimal 84) The result is equal to …
