Abstract: A detection method for the sh
ot boundary detection is proposed based on the integer-to-integer wavelet, and
hierarchical multiresolution. The dissimilarity function is presented by using
wavelet coefficients directly combined with the norms theory, and according to t
he problem of threshold determination difficulty and the feature of confusing gr
adua
l transition with motion easily, the automatic threshold selection method and th
e scheme of twice search by the Tschebyscheff distance are presented. Integer-t
o-integer WT has advantages in speed over the first generation WT and adaptatio
n to dealing with an amount of video data. This method can overcome flash and mo
tion effects efficiently. The experimental results with real video clips demonst
rate that a trade-off between recall and precision is up to more than 98% and
90% no matter what abrupt transitions or the gradual transitions.
