using the K -means algorithm and assign the label of the centroid to each cluster.

These labeled patches are named representative feature patches.

So far, a movie scene s is supposed to be composed of a shot set, that is, s =

{t

1

,,t

n

}. Meanwhile, a panoramic-based key frame p

i

is obtained using the method

depicted in Chapter 4 for each shot t

i

. Specifically, the process for representative

feature patch extraction is depicted as follows:

1. For the panoramic key frame set P ={p

1

, p

2

,,p

}, we extract all the SIFT

features or points in each key
