Abstract

The invention discloses a photo classifying method and a photo classifying device. The photo classifying method comprises the following steps: judging whether a to-be-classified photo has a face area by adopting a face detection algorithm; if the to-be-classified photo has a face area, performing feature extraction on all to-be-classified photos with a face area by use of a lightweight deep model network, and obtaining the face recognition features of the to-be-classified photos and at least one face attribute information; clustering the to-be-classified photos based on at least one face attribute information to obtain multiple clusters; and clustering the to-be-classified photos of each cluster based on the face recognition features to obtain multiple classes of photo albums, wherein each class of photo album stores the to-be-classified photos of the same person. The photo classifying method can realize offline automatic classification of the to-be-classified photos, the classification result is accurate, and the classification speed is high.

Description

technical field [0001] The invention relates to the field of photo classification, in particular to a photo classification method and device. Background technique [0002] As the built-in shooting functions of smart terminals such as smartphones and tablet computers become more and more powerful, and smart terminals such as smart phones and tablet computers are easy to carry, taking pictures with smart terminals such as smart phones and tablet computers has become a daily shooting method for people. important tool. When a smart terminal is used to take photos, the photos will be stored on the smart terminal. When there are a large number of photos, it takes a lot of time to manually search for photos of specific people, and the search results are prone to omissions. In order to overcome the problems of manually searching for photos of characteristic characters, the existing technology provides an automatic photo classification system, including smart terminals and cloud ser...
