Fraunhofer HHI at TRECVID 2004: Shot Boundary Detection System

This paper describes the shot boundary detection and determination system developed at the Fraunhofer Institute for Telecommunications, Heinrich-HertzInstitut, used for the evaluation at TRECVID 2004. The system detects and determines the position of hard cuts, dissolves, fades, and wipes. It is very fast and has proved to have a very good detection performance. As input for our system, we use luminance pixel values of sub-sampled video data. The hard cut detector uses pixel and edge differences with an adaptive thresholding scheme. Flash detection and slow motion detection lower the false positive rate. Dissolve and fade detection is done with edge energy statistics, pixel and histogram differences, and a linearity measure. Wipe detection works with an evenness factor and double Hough transform. The difference between the submitted runs is basically only different threshold settings in the detectors, resulting in different recall and precision values.
