From the literature, STC seems to be the current state-of-the-art for the coding part of steganography. From the description of the method, it appears to me it could be parallelized for GPU. Does developing of STC implementation for GPU even worth it? Are there any existing GPU implementations of STC.
The existing implementations of STC I know of are
- C++/SSE implementation (x86 only) by DDE/Tomas Filler
- Matlab implementation by DDE/Tomas Filler
- Python implementation in stegolab by Daniel Lerch
