ippei ito	cd42e38013	FlannBasedMatcher(LshIndex) in the feature2d optimization for continuance additional train() Current implementation of miniflann is releasing the trained index, and rebuilding the index from the beginning. But, some indexing algorithms like the LSH are able to add the indexing data after that. This branch is implementation of that optimization for LshIndex FlannBasedMatcher in the feature2d.	10 years ago

Roman Donchenko	fec697b390	Silenced a few -Wcast-align warnings in the headers. We don't use -Wcast-align ourselves, but the headers trigger warnings for those users who do, which is not nice.	11 years ago
Roman Donchenko	a9975b144a	Fixed a bug in FLANN resulting in uninitialized accesses. This is fixed upstream in mariusmuja/flann@b615f26, but that fix would break binary compatibility, so I had to make a different one. Since the bug isn't quite obvious, here's an explanation. In the const version of any::cast, if policy is a small_any_policy, its get_value returns its input argument. So r becomes a pointer to obj, and the return value is a reference to a local variable, which is invalidated when the function exits.	11 years ago
