1. A computer-implemented method comprising:

  • storing a first sequence of frames of a video stream in a first buffer;

    generating a second sequence of subframes corresponding to a first portion of respective frames in the first sequence of frames;

    storing the second sequence of subframes in a second buffer;

    generating average intensity values for respective subframes in the second sequence of subframes;

    calculating intensity changes between consecutive subframes in the second sequence of subframes based on the average intensity values;

    determining that a number of intensity changes between consecutive subframes in the second sequence of subframes exceeds an oscillation threshold, wherein respective intensity changes in the number of intensity changes exceed an amplitude threshold; and

    tagging frames in the first sequence of frames as containing an epileptic trigger in response to determining that the number of intensity changes between consecutive subframes in the second sequence of subframes exceeds the oscillation threshold.
