In the Linux kernel-based Distributed and Parallel Security Operating System ( DPSOS), the system security is not assured because of the lack of global user identification and access right managing mechanism. 在基于Linux内核的分布式并行安全操作系统中,由于没有全局一致的用户鉴别和访问权限管理机制,对系统的安全带来危害。
With the combination of a kernel-based spatial information tissue clustering and the bias field correction cost function and extraction of multiple sclerosis lesions, we made a brain MR image segmentation and multiple sclerosis tissue detection system. 结合基于核空间信息的组织聚类分割与偏移场矫正的改进FCM代价函数模型和多发性硬化症病灶提取,做出了一个脑MR图像组织分割与多发性硬化症检测的系统。
