On the performance of bitmap indices for high cardinality attributes
It is well established that bitmap indices are efficient for read-only attributes with low attribute cardinalities. For an attribute with a high cardinality, the size of the bitma...

Presegmentation of high-resolution satellite images with a multifractal reconstruction scheme based on an entropy criterium
The last generation of satellites leads to the very high-resolution images which offer a high quality of detailed information about the Earth's surface. However, the exploita...

An audio watermarking scheme using singular value decomposition and dither-modulation quantization
Quantization index modulation is one of the best methods for performing blind watermarking, due to its simplicity and good rate-distortion-robustness tradeoffs. In this paper, a ne...

A Geometrically Robust Watermarking Scheme Based on Self-Recognition Watermark Pattern
Presently, almost all of the watermarking algorithms resistant to geometric attacks are dependent on the synchronization. In this paper, a geometrically robust watermarking scheme...
