Bitwise operators are calculated by taking a number as a binary. The bitwise algorithms in Python are as follows: Bitwise AND (Bitwise AND of x and Y) Example: 53 = 1 Explanation: 101 11 The same bit is only single-digit 1, so the result is 1 bitwise OR (

int __builtin_ffs (unsigned int x)Returns the x last ( 1\)in the binary representation (the rightmost) is from the back to the first few, such as \ (7368 (1110011001000) \) return \ (4\) . int __builtin_clz (unsigned int x)Returns the number of leading \ (0\) in the binary representation. int __builtin_ctz (unsigned int x)Returns the number of end \ (0\) in the binary representation. int __builtin_popcount (unsigned int x)Returns the number of binary representations in \ (1\) . i

Bitwise OperationsBitwise operations are: And,or,not,xor and so on. When we extract part of an image, these operations are useful when choosing a non-rectangular ROI, often used for logo projection.How to operate this section:The image fixed threshold value of two is valued by the threshold function.Definition: The two value of the image is to set the gray value of the pixel on the image to 0 or 255, that is, the entire image will be visible only blac

Operation Performs a bitwise OR on a variable value and an expression value and assigns the result to the variable. result |= expression Parameters Result Any variable . Expression Any expression . Description Using this operator is equivalent to using the following statement: result = result | expression The |= operator looks at the value of the binary notation of result and expression , and performs a

Operation Performs a bitwise and on the value of a variable and an expression value and assigns the result to the variable. result = expression Parameters Result Any variable . Expression Any expression . Description Using this operator is equivalent to using the following statement: result = result expression The = operator looks at the value of the binary notation of result and expression and performs a

Return the k-th smallest integer Y, for positive th E following equation holds:x + Y =x | Y Where ' | ' denotes the bitwise OR operator. Input the ' the ' input contains an integer t (t For

Operation Performs a bitwise XOR on a variable and an expression and assigns the result to the variable. result ^= expression Parameters Result Any variable . Expression an arbitrary expression . Description Using the ^= operator is equivalent to using the following statement: result = result ^ expression The ^= operator looks at the value of the binary representation of two expressions and performs a
