A method of Internet video subtitle indexing based on video features

Abstract

The invention discloses an Internet video caption indexing method based on video characteristics. The Internet video caption indexing method includes the following steps: as for a video file with text captions, indexes are built, and characteristic values C are determined by rounding numbers generated through the formula (R+G+B) / 10; usual video areas, station captions and advertisement areas are not contained in selected fixed areas; in this way, the characteristic values, namely a color characteristic value sequence (C<1>, C<2>, C<3>, C<4>, ..., C<n>), of the video are obtained, wherein the C<n> represents the characteristic value of the portion, at the 0.1*(n-1)-0.1*n second of the video, and each caption corresponds to a characteristic value subsequence (C<k1>, C<k2>, ..., C<kn>); the video captions are further indexed through the characteristic values to achieve caption matching. The Internet video caption indexing method is formed by building the video characteristic value sequence and the caption characteristic value subsequences, caption indexing can be carried out on videos in different formats, and the Internet video caption indexing method is efficient and accurate.
