Invariant image watermark using Zernike moments
Hyungshin Kim,Heung-Kyu Lee +1 more
TL;DR: A robust image watermark based on an invariant image feature vector using normalized Zernike moments of an image as the vector and is robust with respect to geometrical distortions and compression.
Journal ArticleDOI
Robust image watermarking using local invariant features
TL;DR: The simulation results support the contention that the proposed watermarking method is robust against geometric distortion attacks as well as signal-processing attacks.
Proceedings ArticleDOI
Smart phone power model generation using use pattern analysis
TL;DR: This paper presents an automated power model generation method for smart phone based on usage pattern stored on the phone that can be used to estimate energy consumption of the mobile device.
Book ChapterDOI
Robust Image Watermark Using Radon Transform and Bispectrum Invariants
TL;DR: A new embedding method which allows detection of the watermark when there is no exact inverse function during embedding, which can be used for medical images and shows the invariance of the designed watermark with mathematical proofs.
Journal ArticleDOI
Instruction-Level Power Estimator for Sensor Networks
TL;DR: IPEN is an accurate and fine grain power estimation tool, using an instruction‐level simulator, independent of the operating system, so many different kinds of sensor node software can be simulated for estimation.
