The particle filter algorithm is proposed to process image interpretation for state estimation problem of nonlinear and non-Gaussian system. This algorithm does not involve conventional linearization transform  and has approximated the posterior probability density by a set of discrete particles. Therefore the approximate optimum result is educed. It has a high accuracy and a rapid convergence. Experimental results show that the algorithm be adequate to real time  accuracy and robustness  meets the requirement of image interpretation and possesses practical significance for engineering applications. 2011 IEEE.   Design of image interpretation and data-processing system based on SOPC (EI CONFERENCE) 会议论文 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Wang Z.-Q.; Liu Z.-R.; Xie M.-J. 收藏  |  浏览/下载：11/0  |  提交时间：2013/03/25 In order to follow the development of image interpretation and data-processing system in photoelectric measurement equipments  a kind of hardware acceleration system is designed where MIMD distributed multi-processor architecture is used with SOPC technology. System hardware is composed of FPGA  SDRAM  SRAM  FLASH  and PCI bridge chip. Four Nios II embedded processors are integrated in a single FPGA chip  and communicate with each other by sharing memory. Experimental results indicate that the system meets the requirements of data-processing system in photoelectric measurement equipments and possesses practical significance for engineering applications. 2010 IEEE.   Hepatocellular carcinomas: correlation between time to peak hepatocellular carcinomas enhancement and time to peak aortic enhancement. 期刊论文 Computerized Medical Imaging and Graphics: The Official Jounal of the Computerized Medical Imaging Society, 2009, 卷号: 33, 期号: 4, 页码: 312-316 作者:  Sun X;  Liu C;  Liang C;  Sun C;  Liu S 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/26 Algorithms  Aortography  Carcinoma  Hepatocellular  Female  Humans  Liver Neoplasms  Male  Radiographic Image Enhancement  Radiographic Image Interpretation  Computer-Assisted  Reproducibility of Results  Sensitivity and Specificity  Statistics as Topic  Tomography  X-Ray Computed  *算法  主动脉造影术  癌  肝细胞  肝肿瘤  X线影像增强  放射摄影影像解释  计算机辅助  可重复性  结果  易感性与特异性  体层摄影术  X线计算机
