Course Description:
In the past few years significant progress has been made in Sparse Representation: an efficient representations of data as a (often linear) combination of a few typical patterns (atoms) learned from the data itself. Sparse representation has led to state-of-the-art results in many signal and image processing and analysis tasks. This course will describe effective algorithms for learning such collections of atoms (usually called dictionaries or codebooks), and how to compute such sparse representations with high accuracy. We will discuss both the theoretical foundations of Sparse Representation as well as the state-of-the-art in applying these techniques in areas such as medical imaging, computer animation, computer graphics, computer vision and virtual reality, etc. We will explore current research issues and will cover in depth the associated computational and numerical techniques. This course should be appropriate for graduate students in all areas as well as advanced undergraduate students.
