Sports video wonderful event detection method based on audio emotion driving

The invention relates to a sports video wonderful event detection method based on audio emotion driving. According to the sports video wonderful event detection method based on audio emotion driving, audio information in a video file is fully utilized. The sports video wonderful event detection method based on audio emotion driving comprises the steps that high-level emotion semanteme in an audio file is sensed out in two stages according to the audio emotion sensing technology; an audio classifier based on a layering binary tree support vector machine is constructed in the first stage, and the intermediate-level emotion types are recognized from bottom-level audio characteristics; in the second stage, the high-level emotion semanteme types are obtained from the intermediate-level emotion types through mapping according to the audio emotion mapping technology, and a high-level emotion semanteme fluctuation sequence in an audio stream is smoothly mined after the high-level emotion semanteme is obtained; finally, a wonderful even is obtained by combining mute and emotional emotion semanteme based on the audio emotion semanteme fluctuation sequence. The method is simple, sports video wonderful event detection is driven in the aspect of semanteme by means of audio emotions, and the extracted sports video wonderful event is more wonderful and more effective for users.
