An approach of event-oriented feature abstracting is presented. We devise and improve some media processing algorithms including: text detection in video frames, audio shot detection, scene detection, evaluation of scene significance.

• 设计和改进了部分媒体处理算法，包括：视频帧中的文字探测算法、音频镜头探测算法、融合声像特征的场景检测算法、场景重要程度的评价算法等。
