Abstract

The invention relates to an image clustering method and apparatus, an electronic device and a storage medium. The method comprises the steps of obtaining a face feature and an attribute feature corresponding to each image in an image set; performing clustering processing on the image set by using the similarity of the face features of the images to obtain at least one first class group, the imagesincluded in each first class group being predicted images including the same object; determining a similarity matrix for each first class group by using the face features and the attribute features of each image in each first class group; and on the basis of the similarity matrix corresponding to each first type of group and the face feature of each image in each first type of group, re-clustering each image in each first type of group to obtain at least one second type of group, the images in the second type of groups being optimized and predicted images with the same object. The image clustering precision can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer vision, and in particular to an image clustering method and device, electronic equipment and a storage medium. Background technique [0002] Face clustering is a classic problem in computer vision. Its purpose is to divide massive face data according to identity, and bring together face pictures belonging to the same person. Face clustering has a very important value in the application of multiple fields. For example, in the field of mobile phones and other terminals, face clustering can classify photos of people according to their identities, which is convenient for users to view; in the field of security, face clustering also has very important applications, for example, it can realize one person one file population management, etc. However, face images in practical applications have differences in posture, illumination, expression, occlusion, clarity and other factors. These problems pose a v...
