耿朋勃博士, 將于2023年3月26號(hào)(星期日)上午 9:00-11:00 線下舉辦學(xué)術(shù)報(bào)告.
報(bào)告題目:Signal and Image Reconstruction with Tight Frames via Unconstrained Nonconvex-Analysis Minimizations
報(bào)告地點(diǎn):城關(guān)校區(qū)理工樓 (凌云樓) 402 室
報(bào)告時(shí)間:2023年3月26日 (星期日) 上午 9:00 - 9:40
報(bào)告摘要:In the talk, we introduce an unconstrained analysis model based on the Nonconvex $L1-L2$ minimization for the signal and image reconstruction. We develop some new technology lemmas for tight frame, and the recovery guarantees based on the restricted isometry property adapted to frames. The effective algorithm is established for the proposed nonconvex analysis model. We illustrate the performance of the proposed model and algorithm for the signal and compressed sensing MRI reconstruction via extensive numerical experiments. And their performance is better than that of the existing methods.
