Abstract:Exposing digital image forgeries is a major challenge for photography authentication and forensics investigation, which aims at proving the authenticity of digital photos. In this paper, we introduce a digital image forensics approach based on color coherence to exposing copy-paste-blur forgeries. We first discuss the inherent color coherence introduced by imaging pipeline, and then obtain several statistical features from the coherence characterization. Using the SVM classifier, we reveal traces of copy-paste-blur tampering in photographic forgeries. Experimental results indicate that the proposed method can effectively expose the copy-paste-blur forgeries and localize the tampered regions with high accuracy.
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.
