17 p, 839.0 KB ROI Based Quality Access Control of Compressed Color Image using DWT via Lifting / Phadikar, Amit (MCKV Institute of Engineering (Índia). Department of Information Technology) ; Maity, Santi P. (Bengal Engineering and Science University. Department of Information Technology)
Region-of-Interest (ROI) in an image or video signal contains important information and may be used for access control at various qualities using multiresolution analysis (MRA). This paper proposes a novel quality access control method of compressed color image by modulating the coefficients of ROI at various levels. [...]

10 p, 421.4 KB Redundant Wavelet Watermarking using Spread Spectrum Modulation / Mankar, V. H. (Jadavpur University (Kolkata Índia). Department of Electronics and Telecommunication Engineering) ; Das, T. S. (Jadavpur University (Kolkata Índia). Department of Electronics and Telecommunication Engineering) ; Sarkar, S. (Jadavpur University (Kolkata Índia). Department of Electronics and Telecommunication Engineering)
Spread Spectrum modulation has become a preferred paradigm in many watermarking applications. This paper analyzes the performance of such a blind watermarking scheme under discrete wavelet frame rather than a traditional orthonormal wavelet expansion. [...]

10 p, 133.8 KB Robustness of a Blind Image Watermark Detector Designed by Orthogonal Projection / Jin, Cong (Huazhong University of Science and Technology (Wuhan, Xina). Institute for Pattern Recognition and Artificial Intelligence) ; Peng, Jiaxiong (Huazhong University of Science and Technology (Wuhan, Xina). Institute for Pattern Recognition and Artificial Intelligence)
Blind digital watermarking, which can detect watermark without using the original image, is a key technique practical intellectual property protecting systems and concealment correspondence systems. In this paper, we discussed a blind detection method for the digital image watermark. [...]
