Abstract

The invention discloses an image classification method which is performed in computing equipment and suitable for classifying images according to the faces in the images. The method comprises the steps that multiple images to be classified are acquired; the face in each image is recognized, and each face is corresponding to one face feature vector; the face feature vectors are clustered by using a DBSCAN algorithm based on a first neighborhood radius so that a first clustering result is obtained; the class clusters in the first clustering result are combined according to a second neighborhood radius so that a second clustering result is obtained, wherein the second neighborhood radius is greater than the first neighborhood radius; if the second clustering result includes outliers, the outliers are classified according to a third neighborhood radius so that a third clustering result is obtained, wherein the third neighborhood radius is greater than the first neighborhood radius; and the multiple images to be classified are classified according to the third clustering result. The invention also discloses an image classification application capable of implementing the method and the computing equipment comprising the image classification application.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image classification method, device and computing equipment. Background technique [0002] The rapid development of digital devices has greatly changed people's lives. Taking photos has become more and more convenient, and correspondingly, more and more photos are stored. How to efficiently manage photos has become a real problem. For example, when there are a lot of photos stored, the user needs to classify the photos according to the faces appearing in the photos, that is, group photos of the same person into the same category for easy management. [0003] The classification of photos can be realized by clustering algorithm. However, classic unsupervised clustering algorithms (such as kmeans) often need to manually specify the number of clusters and the initial value of the cluster center, which is not applicable in the application scenario of automatic cl...
