System and method for detecting hazardous vehicles using roadside cameras

Abstract

A system and method for detecting hazard lights of vehicles in a video stream including: spatially downsampling a plurality of sequential frames from the video stream to obtain a plurality of down-sampled pixels in each of the frames; and repeating for one or more of the plurality of down-sampled pixels: generating a time series for the down-sampled pixel by ordering values of the down-sampled pixel from the plurality of sequential frames over time; converting the time series into the frequency domain to obtain a frequency domain representation of the time series; and determining that hazard lights are present in the down-sampled pixel based on the frequency domain representation.
