WebMar 10, 2024 · bitwise_not (source matrix, destination matrix); The bitwise_not () function inverse the source matrix's pixel values and store them in the destination matrix. The source matrix is 'binary_image', and the destination matrix is 'inverted_binary_image'. The following program performs the binary image inversion − Example 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 …
