Biosignal and system modeling: from image processing to system biology

Modeling is the main core of any signal and system processing and analysis. For example, an image can be seen as a matrix (mathematical/deterministic model) and in this base for a conventional processing such as denoising average operator is used. However, as we know this operator doesn’t lead to an optimum result (the produced image is usually blurry). In another point of view, the image can be seen as a random field (statistical model), and so the denoising process is converted to an estimation problem and better denoising results is achieved.
