On Entropy-Compressed Text Indexing in External Memory
A new trend in the field of pattern matching is to design indexing data structures which take space very close to that required by the indexed text (in entropy-compressed form) an...

Hiding Secret Data in an Image Using Codeword Imitation
This paper proposes a novel reversible data hiding scheme based on a Vector Quantization (VQ) codebook. The proposed scheme uses the principle component analysis (PCA) algorithm to...

Automatic Parallelization of Divide and Conquer Algorithms
Divide and conquer algorithms are a good match for modern parallel machines: they tend to have large amounts of inherent parallelism and they work well with caches and deep memory...

H.264 stream replacement watermarking with CABAC encoding
This paper describes a watermarking method to directly embed information into a CABAC entropy coded H.264/AVC stream. In theory, modification of a part of an arithmetically coded ...
