surf用FLANN_INDEX_KDTREE还是FLANN_INDEX_LSH

根据引用\[2\]和引用\[3\]的信息，对于SURF算法，可以使用FLANN_INDEX_KDTREE或FLANN_INDEX_LSH来设置参数。具体来说，可以使用FLANN_INDEX_KDTREE参数来构建索引，如下所示：
index_params = dict(algorithm = FLANN_INDEX_KDTREE, trees = 5)
同时，也可以使用FLANN_INDEX_LSH参数来构建索引，具体的参数设置可以参考FLANN文档。因此，对于SURF算法，可以根据具体需求选择使用FLANN_INDEX_KDTREE或FLANN_INDEX_LSH来设置参数。
