Surveillance cameras have installed in many places because security and safety is becoming important inmodern society. Through surveillance cameras installed, we can deal with troubles and prevent accidents. However, watching surveillance videos and judging the accidental situations is very labor-intensive. So now,the need for research to analyze surveillance videos is growing. This study proposes an algorithm to trackmultiple persons using SURF and background subtraction. While the SURF algorithm, as a person-trackingalgorithm, is robust to scaling, rotating and different viewpoints, SURF makes tracking errors with suddenchanges in videos. To resolve such tracking errors, we combined SURF with a background subtractionalgorithm and showed that the proposed approach increased the tracking accuracy. In addition, the backgroundsubtraction algorithm can detect persons in videos, and SURF can initialize tracking targets with these detectedpersons, and thus the proposed algorithm can automatically detect the enter/exit of persons.
