HIGHTLIGHT DETECTING CIRCUIT AND RELATED METHOD FOR AUDIO FEATURE-BASED HIGHLIGHT SEGMENT DETECTION |
摘要 |
A highlight detecting circuit for detecting a highlight segment within a video signal includes a pitch-tracking module for estimating a plurality of pitch values for an audio signal; a pitch difference detecting module coupled to the pitch-tracking module for computing a plurality of pitch difference values according to the pitch values; and a highlight detecting module coupled to the pitch difference detecting module for determining a starting point and a stopping point of the highlight segment according to the pitch difference values.
