Lossless Compression of Multi-Data Sets and its Variations

For the management of huge amount of data, we have developed a framework in which we address various issues by relating multiple data to each other. We have applied some techniques in data compression and data embedding to typical problems in the framework. We have extended a lossless data compression algorithm based on the BWT to yield a more general scheme, and also developed a syndrome coding algorithm as an efficient data embedding method with an emphasis on its application to gray-scale images.
