Fast image database search using tree-structured VQ
Jau-Yen Chen, Charles A. Bouman, Jan P. Allebach · 2002
We exploit the techniques of tree structured vector quantization (TSVQ), branch and bound search, and the triangle inequality to speed the search of large image databases. Our method can reduce search computation required to locate images which best match a query image provided by a user. While exact search is possible, a free parameter allows search accuracy to be reduced, thereby providing a substantially better speed-up versus accuracy tradeoff.
