Title:
METHOD, DEVICE, SYSTEM, AND SERVER FOR IMAGE RETRIEVAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/174414
Kind Code:
A1
Abstract:
A method, device, system, and server for image retrieval, and a storage medium. The method comprises: acquiring first hash value of a reference image to be retrieved; splitting the first hash value into a preset number of first hash value segments, where the different first hash value segments are different in terms of positional order in the first hash value; positioning a target hash table on the basis of the positional order of the first hash value segments, retrieving from multiple hash value segments in the target hash table second hash value segments identical to the first hash value segments, the target hash table being used for storing hash value segments found on the positional order of the first hash value segments in hash values of images; and retrieving a target image similar to the reference image from candidate images to which the second hash value segments belong. The method reduces the data processing volume in an image retrieval process and increases the efficiency of image retrieval.
