Enhanced multi-bit delta-sigma modulator with two-step pipeline quantizer
—A new delta-sigma Analog-to-Digital Converter (ADC) is presented in this paper. A two-step pipeline ADC is used as the quantizer of this delta-sigma modulator to reduce the quan...

Noise-Shaped Predictive Coding for Multiple Descriptions of a Colored Gaussian Source
It was recently shown that the symmetric multiple-description (MD) quadratic rate-distortion function for memoryless Gaussian sources and two descriptions can be achieved by dithe...

On the tradeoff between security and Robustness of the Trellis Coded Quantization scheme
The steganographic security in the Cachin’s work is defined as the statistical invisibility between the host signal and its marked version. At contrary, the robustness to an at...

Towards an Iterative Classification Based on Concept Lattice
In this paper, we propose a generic description of the concept lattice as classifier in an iterative recognition process. We also present the development of a new structural signat...
