10/3/2012 · meanShift, 均值漂移,在聚类、图像平滑、分割、跟踪等方面有着广泛的应用。meanShift 这个概念最早是由 Fukunage 在 1975 年提出的,其最初的含义正如其名:偏移的均值向量;但随着理论的发展,meanShift 的含义已经发生了很多变化。

MeanShift 该算法也叫做均值漂移,在目标追踪中应用广泛。本身其实是一种基于密度的聚类算法。 主要思路是:计算某一点A与其周围半径R内的向量距离的平均值M,计算出该点下一步漂移(移动)的方

29/6/2016 · Mean Shift is very similar to the K-Means algorithm, except for one very important factor: you do not need to specify the number of groups prior to training. The Mean Shift algorithm finds clusters on its own. For this reason, it is even more of an 「unsupervised」 machine learning algorithm than K-Means. The way Mean Shift
