使用MATLAB实现图像的识别,这是MATLAB官网上面的例子,学习一下. http://cn.mathworks.com/help/vision/examples/image-category-classification-using-bag-of-features.html 这个算法叫做a bag of features approach for image category classification,用于识别小图片里面的是小狗.小猫.还是火车.船等. 首先要下载原材料,用于训练 % L…
在深度学习在图像识别任务上大放异彩之前,词袋模型Bag of Features一直是各类比赛的首选方法.首先我们先来回顾一下PASCAL VOC竞赛历年来的最好成绩来介绍物体分类算法的发展. 从上表我们可以发现,在2012年之前,词袋模型是VOC竞赛分类算法的基本框架,几乎所有算法都是基于词袋模型的,可以这么说,词袋模型在图像分类中统治了很多年.虽然现在深度学习在图像识别任务中的效果更胜一筹,但是我们也不要忘记在10年前,Bag of Features的框架曾经也引领过一个时代.那这篇文章就是要…
Bag of Feature 是一种图像特征提取方法,它借鉴了文本分类的思路(Bag of Words),从图像抽象出很多具有代表性的「关键词」,形成一个字典,再统计每张图片中出现的「关键词」数量,得到图片的特征向量. Bag of Words 模型 要了解「Bag of Feature」,首先要知道「Bag of Words」. 「Bag of Words」 是文本分类中一种通俗易懂的策略.一般来讲,如果我们要了解一段文本的主要内容,最行之有效的策略是抓取文本中的关键词,根据关键词出现的频率确…
