LSB Image Watermarking - Adding Watermarks

LSB image watermarking embeds secret information into the least significant bits of carrier image pixel values, causing minimal visual impact on image quality. Implementation typically involves bitwise operations to replace LSBs while preserving image fidelity.

LSB Image Watermarking - Watermark Extraction

Performs replacement in the spatial domain's LSB (Least Significant Bit), using watermark information, digital watermark digests, or pseudo-random sequences generated from watermarks as the replacement sequence for the LSB bits.
