Abstract

The invention discloses an image retrieval method and device, computer equipment and a storage medium, and relates to the field of artificial intelligence. The image retrieval method comprises the steps of acquiring a to-be-retrieved image; extracting scale invariant feature transformation feature points of the to-be-retrieved image; traversing the scale-invariant feature transformation feature points of the to-be-retrieved image, and acquiring a target feature center by calculations, substituting the index number of the target feature center for each scale invariant feature transformation feature point closest to the feature center over time; and searching in a Hash inverted index table according to the index number of the target feature center to obtain a target historical image. By adopting the image retrieval method, the same or similar images can be quickly retrieved from mass images.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of artificial intelligence, in particular to an image retrieval method, device, computer equipment and storage medium. [0003] 【Background technique】 [0004] Searching for the same or similar images from a large number of historical images has a wide range of application scenarios in the current society. At present, the more common method is to extract the underlying features of historical images, such as color, texture, shape, etc. to make a feature library, and then traverse and calculate the distance between the image features to be retrieved and the historical image feature library to find similar or identical images. The efficiency is low, the process is lengthy, and it is not suitable for large-scale image retrieval scenarios. [0005] 【Content of invention】 [0006] In view of this, the embodiments of the present invention provide an image retrieval method, device, computer equipment and storage med...
