增强视觉 | 计算机视觉 增强现实

时间太少，没空所有好玩的，有价值的都单独更新，只好来个链接大放送：

• BlogOV的更新，探讨一下智能监控中视频检索的问题。其中谈到的用户需求值得学习。

What do users really want? Based on direct user feedback, they want to be able to search for specific people, vehicles or events across the enterprise video system. They want to use what they learn from one search to refine the next. They want to search by example—designating a specific vehicle or person of interest to flag in a database search that might be narrowed by a specific geographic region or time period. They want to create searches and visualize search results on an intuitive geo-interface. And, they don’t want to just be limited to the video archives. Forensic search results need to then become the parameters for real-time rules to find exactly where that white cargo van of interest is right now.

• 谁说计算机视觉没有用，视频检索威力很大啊，虽然是用来检测porn。。。这就是传说中的porn detector。

据说给它1个半小时，就能从500GB的硬盘中扫描7w张图片，然后通过面部分析、肤色分析、器官分析等多种算法找出想要的图片。官方保证它的失误仅保持在1%

• FourSquare算不算是geo-based增强现实呢？这里有教程，手把手教你怎么在黑莓上玩，可惜俺的手机是nokia 1200啊。
  
• People hopper是google最新推出的一个实验产品，有点像face morphing，但是中间过程都是真实的用户头像，没有任何的graphics的成分。
