Abstract: A method and apparatus for detecting a harmful video is provided. The apparatus includes an image collection unit configured to sample a video which is input, and collect N image frames (a natural number larger than or equal to 2) every predetermined period; an image analysis unit including M (a natural number larger than or equal to 2) analyzers, each analyzer analyzing a different characteristic of an image for determining harmfulness of the video; a scheduler configured to determine a plurality of analyzers for analyzing the collected N image frames among the M analyzers, and allocate at least one among the N image frames to each of the plurality of determined analyzers; and a harmfulness determination unit configured to integrate analysis results of the plurality of determined analyzers and determine the harmfulness of the video.

Abstract: Disclosed herein are a method and apparatus for detecting a disaster based on images. The apparatus includes an image capture unit for capturing video using at least one camera and controlling the camera based on a camera control signal received from the outside; a disaster detection unit for generating a disaster log based on the video captured using the camera; a disaster analysis unit for calculating a disaster occurrence probability value based on the disaster log and determining whether to enter a camera control mode based on the disaster occurrence probability value; and a disaster alert unit for warning of a disaster based on a disaster alert request signal.
