报告摘要：Wavelet frames have been successfully applied in various image restoration problems, such as denoising, inpainting, deblurring, etc. However, they are rarely used in geometric applications. Motivated by recently established theoretical connection between wavelet frame based and total variation based image restoration models, we propose here a convex multi-phase segmentation model based on wavelet frame transform. The connection between solutions of the convexied model and the original binary constrained one is established.   Numerical results show that our method can extract many more details than existing variational methods especially when the image contains different scales of structures. The proposed method can be parallelized easily and its efficiency is further improved by a GPU implementation. In addition, we adapt the model for region of interest tracking for ultrasound video segmentation, on incorporating different noise statistics and sequential distance shape priors. The proposed individual frame nonconvex segmentation model is solved by a proximal alternating minimization algorithm and the convergence of the scheme is established based on the recently proposed Kurdyka-Lojasiewicz property. The numerical tests on two real ultrasound video data sets show that the proposed method achieve better results compared to related level sets models and edge indicator shape priors, in terms of both segmentation quality and computational time.

报告摘要：

Beauty is one of the foremost ideas that define human personality. In this talk, various approaches to the comprehension and analysis of human beauty are presented and the use of these theories is outlined. Each set of theories is translated into a feature model that is tested for classification. Selecting the best set of features that will produce the most accurate model for the representation of the human face is a key challenge. This research combines three main groups of features for the classification of female facial beauty by support vector machines. It concentrates on building an automatic system for the measurement of female facial beauty. Our method analyzes the central tenets of beauty, the successive application image processing techniques, and finally the usage of relevant machine learning methods to build an effective system for automatic assessment and enhancement of facial beauty. Plenty of examples will be illustrated during the talk.

报告摘要：

Deep learning has recently achieved great success in many fields such as speech recognition and computer vision, and has so attracted much attention from academic and industry communities. In this talk, I will present some of our recent researches on computer vision based on deep learning. The first is a method for click-through-rate (CTR) prediction in display advertising based on convolutional neural networks. The second is deep learning methods for large scale scene classification. I will also give some examples of deep learning based applications in computer vision such as activity recognition and face detection.

  In addition to deep learning, I will also talk about some other topics such as hashing methods for image retrieval, adaptive affinity matrix for metric learning, a local sparse orthogonal descriptor for image matching etc.

10月20日：丁佐华：Modeling Self-Adaptive Software Systems with Learning Petri Nets

报告题目：Modeling Self-Adaptive Software Systems with Learning Petri Nets

报告人：丁佐华 教授

主持人：刘静 教授

报告时间：10月20日下午13:30-15:00

报告地 点：中北校区数学馆201

报告摘要：Traditional models have limitation to model adaptive software systems since they build only for fixed requirements, and cannot model the behaviors that change at run-time in response to environmental changes. In this paper, an adaptive Petri net is proposed to model a self-adaptive software system. It is an extension of hybrid Petri nets by embedding a neural network algorithm into them at some special transitions. The proposed net has the following advantages:1) It can model a runtime environment; 2) The components in the model can collaborate to make adaption decisions; and 3) The computing is done at the local, while the adaption is for the whole system. We illustrate the proposed adaptive Petri net by modeling a manufacturing system.

报告摘要：In this talk, for the (2+1) dimension nonlocal nonlinear Schr¨odinger (NLS) equation with the self-induced parity-time (PT)-symmetric potential is introduced, which provides two-spatial dimensional analogues of the nonlocal nonlinear Schrodinger (NLS) equation introduced by Ablowitz and Musslimani. General periodic solutions are derived by the bilinear method, these periodic solutions behave as growing and decaying periodic line waves arising from the constant background and decaying back to the constant background again. By taking long wave limits of the obtained periodic solutions, rogue waves are obtained. It is also shown that these line rogue waves arise from the constant background with a line profile and disappear into the constant background again in (x; y) plane.
