Abstract :
The paper discusses the current key frame extraction technology based on the characteristics of teaching video. An experiment system of key frame extraction has been designed based on color feature. The algorithms, which are based on the Histogram average method, content analysis, shot boundary extraction, Kernel Clustering method and so on, have been achieved and and its characteristics are summarized.
