Bits algorithm
WebIn the base paper, author proposed one technique in Image steganography where MSB bits are concentrated more instead of usual LSB bits [1]. In the author's proposed algorithm difference of fifth bit and sixth bit of image byte is carried out and then that difference is compared with secret data. WebNov 11, 2010 · Per experts comments, premature optimization is an evil. The optimization techniques provided are to fine tune your code after finalizing design strategy, algorithm, data structures and implementation. We recommend to avoid them at the start of code development. Code readability is key for maintenance. Thanks to Venki for writing the …

WebAs explained in the previous algorithm, the relationship between the bits of x and x-1. So as in x-1, the rightmost 1 and bits right to it are flipped, then by performing x&(x-1), and storing it in x, will reduce x to a number containing number of ones(in its binary form) less than the previous state of x, thus increasing the value of count in ... WebNov 22, 2010 · X86. On x86 with SSSE3 (Core2 and later, Bulldozer and later), pshufb (_mm_shuffle_epi8) can be used as a nibble LUT to do 16 lookups in parallel.You only need 8 lookups for the 8 nibbles in a single 32-bit integer, but the real problem is splitting the input bytes into separate nibbles (with their upper half zeroed).
