Abstract: MP3是目前最流行的音频文件格式，在网络中得到了广泛应用。在某些音频编辑情况下可能会对MP3文件进行双重压缩，原始MP3文件的量化MDCT系数近似服从拉普拉斯分布，当音频文件经过双重MP3压缩时会改变原始MP3文件的量化MDCT系数分布。通过对量化MDCT系数直方图序列进行傅里叶变换，使用直线拟合傅里叶变换后曲线，获得其波动强度作为特征检测双重MP3压缩。实验结果表明本方法能够有效鉴别双重MP3压缩。
I am not a star professor, but I am working on the road to a star professor of tomorrow. For this reason, self-motivated graduate students are desired to my research group. Self-motivated attitude and initiative are the most important characteristics in our laboratory. Students with preliminary knowledge on signal (image/video) processing and programming skills are most welcome. For your academic trip in my group, I will devote myself to training your FIVE abilities: Intellectual skills, Communication skills, Personality characteristics, Habit of work, Mechanical skills, which are considered as the most important abilities of a graduated student.
