bundle min hash

  • Visual words and bundling

    it was proposed to bundle multiple SIFT features that lie in the same MSER region into a single description [26].

  • 用SIFT获取所有特征点

todo
  • 找center point的邻居节点

    因为是128维的高维向量,所以这里用到了kd-tree,来搜寻邻居特征点

    用到的kdtree的库,flann kdtree

  • mini-hash

    The min-Hashes can be computed by generating multiple random permutations on the range of all visual words and storing them in a lookup table.
