Tomographic Approach for Parametric Estimation of Local Diffusive Sources and Application to Heat Diffusion
We consider localized instantaneous sources that reside in a 2D diffusive environment. Our goal is to reconstruct the induced field from the measurements obtained by distributed s...

High Dimension Lattice Vector Quantizer Design for Generalized Gaussian Distributions
LVQ is a simple but powerful tool for vector quantization and can be viewed as a vector generalization of uniform scalar quantization. Like VQ, LVQ is able to take into account sp...
