Video Analysis Based on Volumetric Event Detection

International Journal of Automation and computing 2010年第3期7卷 365-371页

作者： Jing wang zhi-jie Xu Department of Informatics School of Computing and Engineering University of Huddersfield Huddersfield HD1 3DH UK

During the past decade, feature extraction and knowledge acquisition based on video analysis have been extensively researched and tested on many applications such as closed-circuit television （CCTV） data analysis, large-scale public event control, and other daily security monitoring and surveillance operations with various degrees of success. However, since the actual video process is a multi-phased one and encompasses extensive theories and techniques ranging from fundamental image processing, computational geometry and graphics, and machine vision, to advanced artificial intelligence, pattern analysis, and even cognitive science, there are still many important problems to resolve before it can be widely applied. Among them, video event identification and detection are two prominent ones. Comparing with the most popular frame-to-frame processing mode of most of today＇s approaches and systems, this project reorganizes video data as a 3D volume structure that provides the hybrid spatial and temporal information in a unified space. This paper reports an innovative technique to transform original video frames to 3D volume structures denoted by spatial and temporal features. It then highlights the volume array structure in a so-called ＂pre-suspicion＂ mechanism for a later process. The focus of this report is the development of an effective and efficient voxel-based segmentation technique suitable to the volumetric nature of video events and ready for deployment in 3D clustering operations. The paper is concluded with a performance evaluation of the devised technique and discussion on the future work for accelerating the pre-processing of the original video data.

High Expression of ERCC1 Is a Poor Prognostic Factor in Chinese Patients with Non-small Cell Lung Cancer Receiving Cisplatin-based Therapy

引用

Chinese Journal of Cancer Research 2010年第4期22卷 296-302页

作者： Qing-zhi Guo jie wang Hua Bai Tong-tong An Meina Wu Jun Zhao Lu Yang Jian-chun Duan Yu-yan wang zhi-jie wang Key laboratory of Carcinogenesis and Translational Research （Ministry of Education） Department of Medical Oncology Peking University Cancer Hospital ＆ Institute Beijing 100142 China

Objective： to determine the role of excision repair cross-complementing group 1 gene （ERCC1） and ribonucleotide reductase subunit M1 （RRM1） expression in predicting response and survival in Chinese patients with advanced stage non-small cell lung cancer （NSCLC） treated with platinum-based chemotherapy. Methods： Formalin-fixed, paraffin-embedded biopsy tissues were retrospectively obtained from 160 advanced NSCLC patients. mRNA expression levels of ERCC1 and RRM1 were determined by real-time PCR. Results： Associations between mRNA expression level of ERCC1 and RRM1 and clinic-pathologic parameters were analyzed. One handred and forty two （88.75%） specimens were successfully amplified. mRNA expression level of ERCC1 and RRM1 was negatively associated with tumor response. ERCC1 expression levels ranged from 0.01 to 78.79 [median 0.63, mean 4.25 and standard deviation （SD） 9.23] and RRM1 from 0.00 to 30.91 （median 0.63, mean 0.87 and SD 3.36）. By adopting cut-off values according to median expression levels, we found that MST in patients with low ERCC1 mRNA levels was significantly longer in overall population than in patients with higher levels （18.63 versus 13.69 months, log-rank 5.73, P=0.017）, but we did not found the survival benefit of the patients with low expression level of RRM1. （19.07 versus 14.88, log-rank 1.66, P=0.197）. Further, in the multivariable Cox regression model analysis we found that low level of ERCC1 expression, the presence of weight loss and target therapy, were significant prognostic factors for survival. Conclusion： ERCC1 expression is associated with patients’ survival in Chinese advanced NSCLC patients treated with platinum-based regimen and may serve as a biomarker in predicting tumor response and clinical outcome in the patient population.

Fault diagnosis of a mine hoist using PCA and SVM techniques

引用

Journal of China University of Mining and Technology 2008年第3期18卷 327-331页

作者： CHANG Yan-wei wang Yao-cai LIU Tao wang zhi-jie School of lnformation and Electrical Engineering China University of Mining ＆ Technology Xuzhou Jiangsu 221008 China School of Mechanical and Electrical Engineering Xuzhou Normal University Xuzhou Jiangsu 221116 China Department of Electronics ＆ Information Technology Suzhou Vocational University Suzhou Jiangsu 215104 China

A new method based on principal component analysis (PCA) and support vector machines (SVMs) is proposed for fault diagnosis of mine hoists. PCA is used to extract the principal features associated with the gearbox. Then, with the irrelevant gearbox variables removed, the remaining gearbox, the hydraulic system and the wire rope parameters were used as input to a multi-class SVM. The SVM is first trained by using the one class-based multi-class optimization algorithm and it is then applied to fault identification. Comparison of various methods showed the PCA-SVM method successfully removed redundancy to solve the dimensionality curse. These results show that the algorithm using the RBF kernel function for the SVM had the best classification properties.

AIM: Clinical application and potential complication of percutaneous transsplenic varices embolization (PTSVE) of esophageal or gastrio-fundal varices in patients with hepatocellular carcinoma (HCC) complicated with portal vein cancerous thrombosis (PVCT).METHODS: 18 patients with HCC complicated with PVCT and esophageal or gastrio-fundal varices who underwent PTSVE were collected. The rate of success, complication, mortality of the procedure and postoperative complication were recorded and analyzed.RESULTS: PTSVE were successfully performed in 16 of 18cases, and the rate of success was 89%. After therapy erythrocyte counts decreased in all of the natunts. 5 of patients needed blood transfusion, 2 patients requiredsurgical intervention because of and 11 patients with ascites were alleviated by diuresis. Among these 18patients, the procedure-related mortality was 11% (2/18),one died of acute hepatic failure on the forth day after procedure, another died of acute renal failure on the fifth day. The patients were follow up for 112 mon exceptone. 13of them died of their tumors but none of them experienced variceal bleeding.CONCLUSION: PTSVE is a relatively safe and effective method to treat esophageal or gastrio-fundal varices in HCCpatients with PVCT when percutaneous transhepatic varices embolization (PTHVE) of varices is impossible.

伴随着20世纪历史的变动,中国文学对俄罗斯文学的接受在不同阶段显示出不同的摄取侧重和价值取向,先后经历五四时代对19世纪俄罗斯现实主义文学的吸纳,1930至50年代前期对苏联革命文学、日丹诺夫主义的移植,50年代中期对"解冻"文学的译介及其后对"修正主义文学"的批判,自80年代中期起对"回归文学"的引进,90年代以来对俄罗斯文学的补充接受,以及对苏联解体以来俄罗斯当代文学的接纳。这一漫长的接受史程,既不断刷新着国人心目中俄罗斯文学的原有图像,也折射出接受者民族的历史传统、时代氛围、文化心理和现实需求,还透露出中外文学关系史的某些重要规律。

俄罗斯文学既是俄罗斯民族现代化进程的重要组成部分,又以其特有的方式见证和参与了这一进程。现代化进程中所遭遇的一系列根本问题,如东西方之间的道路选择,知识阶层价值与作用的认定和发挥,以及同现代化的方式和后果相关的忧患意识与乡土情结,等等,同样是文学所不可回避的。俄罗斯文学对这些问题的探索和表达显示出它在现代化进程中不可替代的作用,使其不仅成为现代化运动的生动艺术录影,而且为总结和反思这一行程的历史经验提供了有价值的参照。
