The present invention provides a matching picture search method, a picture search method and apparatuses, and provides a picture matching method, a search method and apparatuses. The matching picture search method comprises: extracting local characteristics of a to-be-queried picture input by a user; matching local characteristics of pictures in a picture database with the local characteristics of the to-be-queried picture, and determining matching proportions of the pictures in the database to the local characteristics of the to-be-queried picture; placing pictures having matching proportions greater than or equal to a first proportion threshold in the database into a picture matching result; and for pictures having matching proportions less than the first proportion threshold and greater than a second proportion threshold in the database, calculating hamming distances between perception hash values of the pictures and a perception hash value of the to-be-queried picture, and placing pictures having hamming distances smaller than a set first distance threshold into the picture matching result, the first proportion threshold being greater than the second proportion threshold. |
