Bag of Visual Word (BoW, BoF, 词袋) 简介 BoW 是传统的计算机视觉方法,用一些特征(一些向量)来表示一个图像.BoW的核心思想是利用一组较为通用的特征,将图像用这些特征来表示,不同图像对于同一个特征的响应也是不同的,最终一个图像可以转化成关于这一组特征的一个频率直方图(向量).这里有个挺清晰的介绍.BoW 常常用在 content-based image retrieval (CBIR) 任务上. 例如下面这张图(来源 Brown Computer Vision…

    WTF is computer vision? Posted Nov 13, 2016 by Devin Coldewey, Contributor   Next Story   Someone across the room throws you a ball and you catch it. Simple, right? Actually, this is one of the most complex processes we've ever attempted to compr…

The picture above is funny. But for me it is also one of those examples that make me sad about the outlook for AI and for Computer Vision. What would it take for a computer to understand this image as you or I do? I challenge you to think explicitly…
