Abstract:A novel approach is presented to detect double compressed MP3 audio by frequency vibration. With the analysis of double compression effect on MDCT (Modified Discrete Cosine Transform) coefficients in MP3 audio, we propose a simple feature called FVV (frequency vibration value) to measure the vibration caused by double compression. The experimental results on challenging dataset show that our method outperforms most of the existing methods in double MP3 compression detection, especially with a second bitrate higher than the first one. Besides, we can also estimate the original bit-rate for a double compressed MP3 by this technique.
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.
