图象规复和边缘提取的连系算法

报告标题标题问题:图象规复与边缘提取的连系协作博弈。

择要:图象规复和边缘提取是图象处置的两大根基标题问题,在退步图象中提取边缘颇具挑衅性,连系实现图象规复和边缘提取很成心义。针对图象规复,操纵已有高效的图象去噪方式界说了一个新的开导式图象正则项;针对边缘提取,改良了一个求图象梯度的优化模子;将二者连系,给出一个协作博弈模子来连系实现图象规复和边缘提取;给出一个求解模子的迭代算法,证实了其收敛性;在恍惚图象和缺失像素图象上的尝试功效标明,所提模子和算法在图象规复和边缘提取两方面都具备杰出的机能。

报告标题标题问题:Deep Learning based Image Segmentation and Restoration with Prior of Variational Model

择要:Deep Convolutional Neural Networks (DCNN) have achieved prominent performance in a series of imageprocessing problems.However, in image segmentation and restoration, DCNN predict the class of each pixel independently tasks. The spatial regularity of the objects in the image is still a problem for these methods. Especially whengiven few training data, DCNN could not perform well in the details. The isolated and scattered small regionsoften appear in all kinds of DCNN segmentation results. The texture restoration is not good enough since lack of nonlocal information in the image restoration. In this talk, we propose a method to consider different priorsincluding regularization and volume persevering in the deep learning method. To be different frompostprocessing technique in many existing methods,we design some new layers for DCNN using the idea of prime-dual method in the variational method. As applications,we apply these proposed layers to several popularsegmentation and restoration DCNNs such Deeplab3+, Unet, DnCNN, the experimental results show that our method can achieve state-of-the-art results on some public datasets such as pascal voc2012.

报告标题标题问题:A new smooth approximation of the maximum function and its applications to imaging problems

择要:In this talk, we present and analyze a smoothing technique  for the maximum function, based on the compensated convex transforms, originally proposed by Kewei Zhang. This type of approximation techniques has an analytical formula which is a $C^{1,1}$ function and a tighter approximation than the log-sum-exp approximation. Moreover, it preserves convexity. Many inverse problems and optimization problems can be formulated as minimization of the maximum of several (convex) functions. We propose smooth approximations to these (non-smooth) minimax problems, which allow first order optimization techniques, and the approximation error can be conveniently estimated. We demonstrate the effectiveness of the proposed method through numerical examples in Pott's model for multiphase partition, robust optimization, the computation of the Euclidean distance between two closed convex sets, and in implicit shape blending.

报告标题标题问题:Image decomposition and restoration based on the adaptive direction total variation regularization

择要:With the development of the deep learning, we need many labeled data to improve the learning  accuracy by employing some efficient numerical methods without any manual work. So the data clustering method has received extensive attention in these fields. In this report, we want to propose a new clustering method via modifying the classic Cheeger cut model. Since the model is nonconvex and nonsmooth, we use the linearization scheme to transform it into the easily solvable optimization and then use the ADMM to solve it. Numerical experiments demonstrate that the proposed method is competitive with the current state of the art in some data clustering methods.
