Audio signal segmentation and classification for scene-cut detection

A scene is regarded as a basic unit of audiovisual material, and thereby the boundaries between two adjacent scenes, which are called scene-cuts, must be detected in advance for audiovisual indexing. This paper proposes a scene-cut detection method. Since scene-cuts are associated with a simultaneous change of visual and audio characteristics, both audio and visual analyses are required for the scene-cut detection. For the audio signal analysis, the proposed method utilizes an audio signal segmentation and classification method using fuzzy c-means clustering, which has been proposed by the authors. For the visual signal analysis, the proposed method utilizes some visual segmentation methods. By using these methods simultaneously, the proposed method can accurately detect the scene-cuts, and thereby it is highly valuable for the preprocessing for audiovisual indexing. Experimental results performed by applying the proposed method to real audiovisual material are shown to verify its high performance.
