Operadores BITWISE (AND-OR-NOT-XOR) con OpenCV y Python
WebBackground Bitwise NOT ~ Python’s bitwise NOT operator ~x inverts each bit from the binary representation of integer x so that 0 becomes 1 and 1 becomes 0. This is semantically the same as calculating ~x == -x-1. For example, the bitwise NOT expression ~0 becomes -1, ~9 becomes -10, and ~32 becomes -33. WebBitwise operators are used to compare (binary) numbers: Operator Precedence Operator precedence describes the order in which operations are performed.
