Call for
This long-running series provides a forum for presentation of results in theory and applications of sparse representations. Originally, the focus of this conference series was on wavelets. The lasting impact of wavelet theory is the rise of sparsity as a modeling paradigm that complements bandwidth and provides tremendous opportunities in representation, estimation, and acquisition of signals. Accordingly, in the course of many successful meetings the topics have expanded and now encompass the entire domain of the theory and applications of all signals that have sparse representations or approximations. The conference welcomes original papers on the mathematics of signal and image processing and analysis and in all areas of mathematical and computational sciences that are affected fundamentally by the choice of image/signal representation. The series distinguishes itself by successfully straddling disciplinary boundaries; it has drawn preeminent researchers in mathematics, signal and image processing and analysis, computer vision, medical imaging, neuroscience, physics, and other fields. It focuses on novel applications of signal and image analysis, data and network science by refinements of existing techniques, and new theoretical developments.
