传统的图像检索过程,先通过人工对图像进行文字标注,再利用关键字来检索图像,这种依据图像描述的字符匹配程度提供检索结果的方法,简称“以字找图”,既耗时又主观多义.基于内容的图像检索客服“以字找图”方式的不足,直接从待查找的图像视觉特征出发,在图像库(查找范围)中找出与之相似的图像,这种依据视觉相似程度给出图像检索结果的方式,简称“以图找图”.基于内容的图像检索分为三个层次: (1)依据提取图像本身的颜色.形状.纹理等低层特征进行检索: (2)基于图像的低层特征,通过识别图像中的对象类别以及对象之间…

主要参考维基百科Bag of Word 在DLP领域里,bow(bag of word)是一个稀疏的向量,向量的每个元素记录词的出现次数,相当于对每篇文章都关于词典做词的直方图统计.同样的道理用在computer vision领域,图像由一些基础的特征构成,每幅图像就是对这些特征的一个统计分布,在做图像分类时会假设相似图像他们的特征统计分布也符合一定的模型.于是从这句话里就可以把以bow模型的图像分类问题分解成以下几步: 1.1 特征检测: 1.2 特征描述:1.3  码本生成(bow向量) 2…
