Abstract

The invention relates to an image processing method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the feature extraction of a to-be-processedimage, and obtaining a first feature of the to-be-processed image; according to the first feature and class center features of a plurality of reference image classes in a feature library, determiningan image class of the to-be-processed image; and under the condition that the image category of the to-be-processed image is a first category in the plurality of reference image categories, updating acategory center feature of the first category according to the first feature and a plurality of pieces of feature information of the first category in the feature library. According to the embodimentof the invention, the image retrieval speed and accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an image processing method and device, electronic equipment, and a storage medium. Background technique [0002] With the development of related technologies, face retrieval has been widely used, especially when solving crimes in the public security industry, it is necessary to search in massive portrait databases based on unidentified suspect images. The commonly used face retrieval method is to compare the retrieved pictures with the database pictures one by one. When there are a large number of images in the database, the amount of computation for face retrieval increases significantly, resulting in slow retrieval speed and low recall rate. Contents of the invention [0003] The disclosure proposes an image processing technical solution. [0004] According to an aspect of the present disclosure, an image processing method is provided, including: performing f...
