Abstract
An image search method and an apparatus may include acquiring an image to be searched; extracting a multi-scale feature of the image to be searched; determining a hash value of the image to be searched according to the multi-scale feature; and obtaining original images similar to the image to be searched by comparing the multi-scale feature of the image to be searched with a multi-scale feature of each original image corresponding to a hash bucket to which the hash value belongs.
Claims19
An image search method, comprising:
- acquiring an image to be searched;
- extracting a multi-scale feature of the image to be searched;
- determining a hash value of the image to be searched according to the multi-scale feature;
- and
- obtaining original images similar to the image to be searched by comparing the multi-scale feature of the image to be searched with a multi-scale feature of each original image corresponding to a hash bucket to which the hash value belongs;
- wherein before obtaining the original images similar to the image to be searched, the method further comprises:
- acquiring a plurality of original images;
- extracting a multi-scale feature of each of the original images, and determining a hash value of the original image according to the multi-scale feature of the original image;
- generating an index library according to the original images and hash values of the original images, wherein the index library comprises at least one hash bucket, and each of the at least one hash bucket comprises at least one of correspondences between the hash values and the original images;
- and
- generating a multi-scale feature library according to the original images and multi-scale features of the original images, wherein the multi-scale feature library comprises at least one correspondence between the original images and the multi-scale features.

- wherein the method further comprises:
- extracting a scale-invariant feature of the image to be searched;
- and
- obtaining original images identical to the image to be searched by comparing the scale-invariant feature of the image to be searched with a scale-invariant feature of each original image corresponding to the hash bucket to which the hash value belongs.
