Abstract

The invention provides an image search method and device. The image search method comprises the steps of acquiring a current image sent by a client, extracting current features from the current image, and searching a reverse index database according to the current features to obtain reverse index values, wherein the reverse index database comprises a plurality of chain tables in one-to-one correspondence to the features of the image; carrying out merging sorting on the corresponding chain tables according to the reverse index values; returning a search result to the client according to a processing result so as to display the search result to a user conveniently. According to the image search method and device, the current features of the current image are extracted, the reverse index database comprising the chain tables is searched according to the current features to obtain the reverse index values, merging sorting is carried out on the corresponding chain tables according to the reverse index values, and the search result is displayed to the user, so that operation is convenient, implementation is easy, and the inconvenience of obtaining a result through character input is avoided.
