Abstract:从数字图像中盲检测数码相机采用的CFA插值算法,可以为数字图像取证提供重要的技术手段.该文基于线性插值模型,利用协方差矩阵构建插值系数方程组,并将估计的插值系数构成特征向量空间,采用支持向量机作为分类工具,提出了一种对不同的CFA插值算法进行准确分类的盲检测方法.实验表明,该文方法对于不同的CFA插值算法均能达到较高检测正确率.同时,相比现有的CFA插值检测方法,该文算法对加性高斯白噪声和有损JPEG压缩具有更好的鲁棒性.
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.
