Abstract :
The paper presents a novel, real-time, minimal-latency technique for dissolve detection which handles the widely varying camera techniques, expertise, and overall video quality seen in amateur, semi-professional, and professional video footage. We achieve 88% recall and 93% precision for dissolve detection. In contrast, on the same data set, at a similar recall rate (87%), DCD (double chromatic difference) has more than 3 times the number of false positives, giving a precision of only 81% for dissolve detection.
