Abstract:In this paper, we propose a JPEG image tampering detection method that is robust to post-processing operations such as rotation, resizing, feathering, etc. By finding image blocks that are lack of double compression artifacts, the proposed method can localize the tampered regions. Gray Level Co-occurrence Matrix (GLCM) of the DCT coefficients is used to reveal the double compression artifacts of images. Experiments are designed to show the validity of the proposed method for double compression detection and localization for tampered regions. The proposed method needn't to estimate the first quality factor as most of the previous works do and still works well even when the tampered images are recompressed at a low quality factor.
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.
