Many algorithms have been proposed for detecting video shot boundaries
and classifying shot and shot transition types. Few published studies
compare available algorithms, and those that do have looked at limite
d range of test material. This paper presents a comparison of several
shot boundary detection and classification techniques and their variat
ions including histograms, discrete cosine transform, motion vector, a
nd block matching methods. The performance and ease of selecting good
thresholds for these algorithms are evaluated based on a wide variety
of video sequences with a good mix of transition types. Threshold sele
ction requires a trade-off between recall and precision that must be g
uided by the target application. (C) 1996 SPIE and IS&T.
