Miki Elad - Sparse Modeling of Graph structured Data and Images

Miki Elad of Technion - Sparse Modeling of Graph-Structured Data ... and ... Images
Images, video, audio, text documents, financial data, medical information, traffic info -- all these and many others are data sources that can be effectively processed. Why? Is it obvious? In this talk we will start by discussing "modeling" of data as a way to enable their actual processing, putting emphasis on sparsity-based models. We will turn our attention to graph-structured data and propose a tailored sparsifying transform for its dimensionality reduction and subsequent processing. We shall conclude by showing how this new transform becomes relevant and powerful in revisiting ... classical image processing tasks.
