FGBC-iDistance:fine-grained bit-code filter based high-dimensional index

In the high-dimensional vector retrieval,distance computation is a very time-consuming operation,the current research trend is to reduce the distance computation using divide and conquer algorithm.iDistance algorithm divides the vector space into subspace of clustering by pivot,BC-iDistance algorith...
