Resumo: | |||||||||||||
Massive amounts of video are uploaded on video-hosting platforms
every minute. This volume of data presents a challenge in controlling the
type of content uploaded to these video hosting services, for those platforms
are responsible for any sensitive media uploaded by their users. There
has been an abundance of research on methods for developing automatic
detection of sensitive content. In this dissertation, we define sensitive
content as sex, extreme physical violence, gore, or any scenes potentially
disturbing to the viewer. We present a sensitive video dataset for binary
video classification (whether there is sensitive content in the video or not),
containing 127 thousand tagged videos, Each with their extracted audio and
visual embeddings. We also trained and evaluated four baseline models for
the sensitive content detection in video task. The best performing model
achieved 99 percent weighed F2-Score on our test subset and 88.83 percent on the
Pornography-2k dataset.
