2.5. Lossless Compression–Based Schemes

2.5.1. Lossless Bit-Plane Compression in the Spatial Domain

Fridrich's group produced profound research on lossless data hiding techniques and developed a number of algorithms. This group proposed two techniques in this area [6]. The first technique, based on robust spatial additive watermarks, utilizes the modulo addition to embed the hash of the original image. The second technique uses the JBIG Lossless Compression Scheme [49] for losslessly compressing the bit-planes to make room for data embedding. To provide sufficient room for data embedding for the second technique, it is usual to compress the high level bit-plane. This mostly leads to visual quality degradation. Since the method aims at authentication, ...
