Abstract:针对实际取证场景中经网络传输的JPEG压缩图像,分析了基于彩色滤波阵列(CFA)插值系数特征、局部二进制模式(LBP)以及图像质量(IQM)和高阶小波统计特征这3种典型的相机型号来源取证方法的性能,评估了社交平台和网络媒体情况下已有来源取证算法的性能.实验结果表明,随着图像压缩质量的下降,相机型号来源鉴别准确率迅速下降,已有方法在实际应用中的性能仍然有待提高.
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.
