报告摘要：

  In this talk, I will first give a brief review of the recent developments of wavelet frames, especially, the unitary extension principle. The unitary extension principle provides a great flexibility in designing tight frame wavelet filters and makes constructions of tight frame wavelets adapted to practical problems possible. In the second part of my talk, I will focus on new algorithms based on wavelet frames designed via the unitary extension principle for various applications, such as deconvolution, high resolution image reconstructions, noise removal, image inpainting. The numerical simulations show that the new algorithms are efficient. An analysis of theoretical foundations of these algorithm is also given.
