In content-based image retrieval system,describing and extracting image's feature is a key step.This paper presents a new retrieval method using image's features described by quadtree,which is an effective method using low dimension feature.It is especially fit for retrieval in the case of lower recall rate or pre-retrieval in large scale image library.
