Improved dual-mode compressive tracking integrating balanced colour and texture features

《改进的集成平衡颜色和纹理特征的双模压缩跟踪》摘要:将跟踪问题视为分析目标和背景信息的分类问题的判别跟踪方法可以实现最先进的性能。作为一个高性能判别器,压缩跟踪近来受到很多关注。然而,当物体遭受长时间遮挡,以及严重的外观和光照变化时,很容易导致跟踪失败。为解决这一问题,作者考虑平衡特征表示以及双模分类器的构造,开发了基...

tomcat中使用response.encodeURL()或response.encodeRedirectURL()实现回话追踪(session tracking)技术

HTTP是一种无连接的协议,如果一个客户端只是单纯地请求一个文件(HTML或GIF),服务器端可以响应给客户端,并不需要知道一连串的请求是否来自于相同的客户端,而且也不需要担心客户端是否处在连接状态。但是这样的通信协议使得服务器端难以判断所连接的客户端是否是同一个人。当进行Web程序开发时,我们必须想办法将相关的请求结...
