“…As part of this method, we also define an algorithm for finding an adequate number of clusters based on the silhouette score. We investigate to what extent this method can be used as the core to leverage and enhance some innovative applications, especially in three different practical and important tasks: Video Face Recognition [2], Educational Video Recommendation [4], and Subtitles Positioning in 360-Video [3].…”

The popularity of platforms for storing and transmitting video content has created a substantial volume of video data. Given a set of actors present in a video, generating metadata with the temporal determination of the interval in which each actor is present and their spatial 2D localization in each frame in these intervals can facilitate video retrieval and recommendation. In this work, we investigate Video Face Clustering for this spatio-temporal localization of actors in videos. We first describe our method for Video Face Clustering in which we take advantage of face detection, embeddings, and clustering methods to group similar faces of actors in different frames and provide the spatio-temporal localization of them. Then, we explore, propose, and investigate innovative applications of this spatio-temporal localization in three different tasks: (i) Video Face Recognition, (ii) Educational Video Recommendation and (iii) Subtitles Positioning in 360-video.

“…However, this method can be used in a hybrid recommendation approach, that combines both textual and audiovisual information from the video to create clusters. The results of this application were published at relevant multimedia conference (63). Video Face Clustering for Subtitles Positioning in 360-Videos In (64), we proposed an authoring model for interactive 360-video.…”
