Minmax strategies for QIM watermarking subject to attacks with memory
This paper examines the role of attacker’s memory in Quantization Index Modulation (QIM) watermarking systems. First we derive the attacker’s noise distribution that maximizes...

Subband Image Coding Using Cosine Modulated Filter Banks with Perfect Reconstruction and Linear Phase
lye propose a lossy image coding scheme based on the recently introduced even-stacked cosine modulated filter banks (CSIFBs) that allow linear phase filters in all channels. We des...
