Abstract:数字相机的普及和图像处理软件的应用使得数字图像正面临着被随意篡改和伪造的威胁。本文针对模糊润饰后的数字伪造图像,提出了一种利用色彩一致性进行定位检测的数字图像取证方法。通过从图像块中提取全局色调率,色调变化率以及异常色调率三个特征,来量化描述模糊润饰操作对成像系统引入的图像局部色彩一致性的破坏。利用支持向量机分类器进行原始像素点和模糊像素点的分类,并以此对模糊润饰的伪造图像区域进行定位。实验表明,该方法能够对模糊润饰的图像进行有效检测和定位。
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.
