Introduction (1)IVPR问题: 根据一张图片从视频中识别出行人的方法称为 image to video person re-id(IVPR) 应用: ① 通过嫌犯照片,从视频中识别出嫌犯: ② 通过照片,寻找走失人口. (2)图片-视频行人匹配问题的描述: (3)IVPR的难点: ① 图像.视频的特征不同:视频包含视觉外貌特征(visual appearance features)和时空特征(spatial-temporal features),而图片只包含视觉外貌特征: ② I…

http://blog.csdn.net/zouxy09/article/details/8775360 一.概述 Artificial Intelligence,也就是人工智能,就像长生不老和星际漫游一样,是人类最美好的梦想之一.虽然计算机技术已经取得了长足的进步,但是到目前为止,还没有一台电脑能产生“自我”的意识.是的,在人类和大量现成数据的帮助下,电脑可以表现的十分强大,但是离开了这两者,它甚至都不能分辨一个喵星人和一个汪星人. 图灵(图灵,大家都知道吧.计算机和人工智能的鼻祖,分别对应于…

十.总结与展望 1)Deep learning总结 深度学习是关于自动学习要建模的数据的潜在(隐含)分布的多层(复杂)表达的算法.换句话来说,深度学习算法自动的提取分类需要的低层次或者高层次特征. 高层次特征,一是指该特征可以分级(层次)地依赖其他特征,例如:对于机器视觉,深度学习算法从原始图像去学习得到它的一个低层次表达,例如边缘检测器, 小波滤波器等,然后在这些低层次表达的基础上再建立表达,例如这些低层次表达的线性或者非线性组合,然后重复这个过程,最后得到一个高层次的表达. Deep lea…
