摘要

 Many important applications in computer vision and machine learning can be formulated as bi-linear problems, e.g., blind image deblurring, vision in bad weather condition, dictionary learning, and many others. These problems are challenging ill-posed non-linear inverse problems yet see its wide applications in practice. In this talk, I will represent several models and techniques that provide feasible solutions to these challenging bi-linear problems, which is built upon  several mathematical tools, including wavelet tight frames, sparse approximation, L1-norm relating regularization, and optimization methods for non-convex problems.
