报告题目:Iterative Optimization Algorithms in Image Recovery are Deep Networks?

主持人:孟德宇(西安交通大学


报告摘要:In this talk, I will show that many iterative optimization algorithms in image restoration and reconstruction can be modeled as deep networks, by which the parameters in iterative algorithm and the corresponding energy function can be discriminatively learned for specific tasks from training images. I will first introduce our proposed discriminative parameter learning approach in Markov random field models [CVPR 2011], which motivates our current research along this direction. Then I will show that the iterative shrinkage in signal processing [IEEE TIP 2015], ADMM (Alternating Direction Method of Multipliers) algorithm optimizing a compressive sensing model can be formulated as deep networks. These deep networks are non-conventional, and achieved state-of-the-art results in image restoration and compressive sensing MRI.

I will also briefly introduce our work on part-based image recognition, deep learning-based image deblur and human organ segmentation.
