Theoretical analysis of musical noise in Wiener filtering family via higher-order statistics
Recently, one of the authors has reported that the amount of generated musical noise is strongly correlated with higher-order statistics of the power spectra. On the basis of this...

QIM-Based Histogram-Preserving and High Capacity Steganography for JPEG Images
- We propose a secure steganographic approach with a high capacity. We first use small neighborhoods of the original histogram to calculate the minimum remapping from a histogram t...

Robust SS watermarking with improved capacity
Robustness is a key attribute of spread spectrum (SS) watermarking scheme. It is significantly deteriorated if one tries to achieve high embedding rate keeping other parameters u...

Multiplexed clustered-dot halftone watermarks using bi-directional phase modulation and detection
We present a method for embedding and detection of visual watermark patterns in printed images that use clustered-dot halftones in the printing process. The method allows two inde...

Static analysis of processor stall cycle aggregation
Processor Idle Cycle Aggregation (PICA) is a promising approach for low power execution of processors, in which small memory stalls are aggregated to create a large one, and the p...
