K-means算法是一种动态聚类方法,这种方法先选择若干样本作为聚类的中心,在按某种聚类准则(通常采用最小距离原则)使各种样本向各个中心积聚,从而得到初始的分类,然后,判断分类的合理性,如果不合理,就修改分类,如此反复的修改聚类的迭代运算,直到合理为止。-K-means algorithm is a dynamic clustering method, this method, select the number of samples as a cluster center in the clu

VLAD VLAD可以理解为是BOF和fisher vector的折中
BOF是把特征点做kmeans聚类,然后用离特征点最近的一个聚类中心去代替该特征点,损失较多信息;
Fisher vector是对特征点用GMM建模,GMM实际上也是一种聚类,只不过它是考虑了特征点到每个聚类中心的距离,也就是用所有聚类中心的线性组合去表示该特征点,在GMM建模的过程中也有损失信息;
VLAD像BOF那样,只考虑离特征点最近的聚类中心,VLAD保存了每个特征点到离它最近的聚类中心的距离;

K-means算法是集简单和经典于一身的基于距离的聚类算法
采用距离作为相似性的评价指标,即认为两个对象的距离越近,其相似度就越大。
该算法认为类簇是由距离靠近的对象组成的,因此把得到紧凑且独立的簇作为最终目标。(K-means algorithm is a distance based clustering algorithm which is simple and classic.
Distance is used as a similarity evaluation index, t
