2024.12

Implemented embeddings

• MiPOD
• F5
• S-UNIWARD
• WOW

Improvements

• LSB can now embed with efficiency 2 (by default), but also at the embedding bound

Additionally, following was added

• simulator for binary changes
• distortion-limited sender
• MiPOD LRT for benchmarking of stego security
• coding-related features, e.g., Hamming efficiency and generator of generator of robust Soliton-distributed H matrix

2024.09

Fixed the source distribution.

2024.06

Added spatial embedding

• HILL

2024.03

Added first spatial embeddings.

• HUGO
• LSB (replacement and matching, grayscale and color)

2023.12

First release.

Implemented embeddings:

• J-UNIWARD
• UERD
• EBS
• nsF5

API on three abstraction levels:

• high-level (single call to embed)
• mid-level (moderate abstraction, separated cost from simulator)
• low-level (full access to cost computation, probability conversion, and simulator)
