My research focuses on the development of mathematical modeling and computational methods for solving pratical problems in imaging and vision science. The implementations of some methods can be found in this page.

- Image de-raining via discriminative sparse coding - Data-driven non-local frame and image deconvolution - L0 norm based dictionary learning for sparse coding - Data driven tight frame construction and image denoising - Robust image deconvolution in the presence of kernel error - Video restoration by robust low rank matrix approximation - Wavelet frame based single-image blind image deblurring
