jpegadv_f5_detect
Detects F5 steganography in JPEG files by analyzing DCT coefficient histograms for characteristic zero excess and dip at +/-1 from matrix embedding.
Instructions
F5 steganography detection. F5 embeds data by decrementing the absolute values of DCT coefficients toward zero (shrinkage). Detects the characteristic excess of zeros relative to near-zero coefficients and the histogram dip at +/-1 that F5 matrix embedding produces.
