Abstract： Object detection is the basis of intelligent analysis, however, in the scene of illumination, shadow and clutter background, the problems of object misjudgment and unreasonable clustering is often appeared. Aiming at the above problems, propose a HVS-based object detection algorithm, which can optimize the error judgment and segmentation, and then accorded to the tracking characteristic of HVS and the continuity of object movement, combine the detection results of adjacent frames to achieve completely and accurately extraction object area. Finally, the simulation experiment based on the actual acquisition videos show that the proposed algorithm is more accurate and have good effect and in complex background.

Abstract：随着我国高速铁路和宽带无线通信技术的发展，在高铁环境下提供宽带无线通信的需求日益强烈。目 前高铁采用的窄带 GSM-R（Global System for Mobile Communications on Railways）只能提供 200kbps 以下 的数据传输速率，无法满足未来高铁展开视频监控、旅客多媒体等新业务的需求。必须发展面向高铁优化的宽带无线通信系统，才能为高铁的运营、控制，为旅客提供稳定，可靠，高质量的宽带无线通信服务。本文针对高铁高速移动、位置可预期等特点，分析了面向高铁的宽带无线通信系统在网络架构、资源管理 和物理层空口等核心技术上面临的挑战，并提出了解决问题的思路。
