DCT-Block Steganography for Grayscale Images with Histogram-Aware Embedding
Frequency-Domain Data Hiding Pipeline
Transform-domain steganography exploits the human visual system's lower sensitivity to spectral modifications. By decomposing a grayscale carrier image into localized frequency blocks, secret data can be distributed across transform coefficients while preserving visual fidelity and statistical consistency. ...
