Detection of photosensitive triggers in video content

A system comprising:

• one or more processors;
• and
• one or more computer-readable storage media storing program instructions which, when executed by the one or more processors, are configured to cause the one or more processors to perform a method comprising:
• storing a sequence of subframes in a buffer, wherein the sequence of subframes comprise portions of a plurality of frames of video data;
• generating average intensity values for respective subframes in the sequence of subframes;
• calculating a plurality of intensity changes between consecutive subframes in the sequence of subframes based on the average intensity values;
• determining that each of the plurality of intensity changes exceeds an amplitude threshold;
• determining that the plurality of intensity changes exceeds an oscillation threshold;
• and
• modifying respective frames corresponding to the sequence of subframes to mitigate an epileptic trigger in the video data.

A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising instructions configured to cause one or more processors to perform a method comprising:

• generating average intensity values for respective subframes in the sequence of subframes;
• calculating a plurality of intensity changes between consecutive subframes in the sequence of subframes based on the average intensity values;
• determining that each of the plurality of intensity changes exceeds an amplitude threshold;
• determining that the plurality of intensity changes exceeds an oscillation threshold;
• and
• modifying respective frames corresponding to the sequence of subframes to mitigate an epileptic trigger in the video data.
