Portrait clustering method and device and storage medium

The invention discloses a portrait clustering method and device and a storage medium, and the method comprises the steps: obtaining an image sequence; extracting a portrait picture in the image and portrait features in the portrait picture, and performing clustering processing to obtain clustering results of different portrait features; according to relevance of different portrait features, clustering results of the different portrait features are fused, and the same kind of portraits, the suspected same kind of portraits and different kinds of portraits are obtained; re-weighting the similarity of different portrait features of the suspected targets in the same kind of suspected portraits to obtain the comprehensive similarity of the suspected targets; and comparing the comprehensive similarity with a preset threshold, and classifying the suspected same type of portraits into the same type of portraits or different types of portraits. According to the method, the suspected targets of the suspected same-type portraits are subjected to secondary verification, so that the suspected same-type portraits are further accurately classified, data which cannot be in a middle section are eliminated, and the recall rate of clustering is effectively increased.
