The invention discloses an image retrieval method, a device, and electronic equipment. The method comprises the steps of obtaining a to-be-retrieved first image; obtaining image feature information ofthe first image; at least performing hash encoding on the image feature information to obtain a first hash encoding value; performing similarity calculation on the first hash coded value and a secondhash coded value in a coded set to obtain a target hash coded value in the coded set, wherein the code set comprises a plurality of second hash code values, each second hash coded value corresponds to a frame of second image, the second hash coded value is a hash coded value obtained by at least performing hash coding on image feature information of a second image corresponding to the second hashcoded value, and the target hash coded value is a second hash coded value of which the similarity value with the first hash coded value in the coded set meets a similarity condition; and obtaining atarget image corresponding to the target hash coded value.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular to an image retrieval method, device and electronic equipment. Background technique [0002] In the currently commonly used image retrieval schemes, image content is analyzed to extract low-level features of the image, such as color, texture, shape, etc., and then similarity matching is performed based on these low-level features to obtain similar images and realize image retrieval. [0003] Since the low-level features of the image are used for similarity matching in this scheme, the calculation of similarity matching will be large due to the high dimension of the low-level features, resulting in low efficiency of image retrieval. Contents of the invention [0004] In view of this, this application provides an image retrieval method, device and electronic equipment, as follows: [0005] An image retrieval method, said method comprising: [0006] obtaining the...
