MATLAB Implementation of LSB Algorithm - The Simplest Steganography Technique

Implementation in Spatial Domain The core principle of LSB digital watermarking: Modifying the least significant bit of binary images doesn't affect visual perception. Based on this, watermark information can directly replace the least significant bits of digital images. The embedding process consists of three main steps: 1. Convert spatial domain pixel values from decimal to binary representation using bit-level operations 2. Replace the least significant bits of corresponding data with each bit of binary watermark information through bit manipulation 3. Convert the watermarked binary data back to decimal pixel values to obtain the watermarked image using appropriate conversion functions
