Key Words:图像取证;边缘振荡;USM锐化;支持向量机

Abstract:针对Photoshop中USM(Unsharp Mask)锐化篡改,提出了一种新的取证算法.分析和讨论了锐化图像引起边缘振荡的原因,并根据这种振荡现象提取阶跃边缘点特征,使用支持向量机对阶跃边缘点分类.该算法能够有效地检测出图像是否经过锐化操作,能够定位出图像的锐化区域,并对重压缩具有鲁棒性.

Pre One:Double compression detection based on Markov model of the first digits of DCT coefficients

Next One:多特征的手机图像来源取证

Profile

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.
