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) ; Sarkar, S. K. (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. [...]

(Indian Statistical Institute (Kolkata, Índia). Advanced Computing and Microelectronics Unit)
Since the inception of successful rasterization of curves and objects in the digital space, several algorithms have been proposed for approximating a given digital curve. All these algorithms, however, resort to thinning as preprocessing before approximating a digital curve with changing thickness. [...]
