Description: Image Forensic Analyses that Elude the
Human Visual System
While historically we may have been overly trusting of photographs, in recent years there has been a backlash
of sorts and the authenticity of photographs is now routinely questioned. Because these judgments are often
made by eye, we wondered how reliable the human visual system is in detecting discrepancies that might arise
from photo tampering. We show that the visual system is remarkably inept at detecting simple geometric
inconsistencies in shadows, reflections, and perspective distortions. We also describe computational methods
that can be applied to detect the inconsistencies that seem to elude the human visual system.

Description: Since the birth of digital data hiding, image authentication has been one of its most widespread applications. During the first years, aside a few numbers of works, this application was limited to verifying the integrity of the image or locating its tampered regions. Nowadays, these watermarks are designed in sophisticated ways to not only localize the image tampering, but also recover the lost content in those areas. In tampering protection and self-recovery schemes, the goal is to embed a representation of the original image into itself in a way to efficiently compromise between three design parameters the quality of the watermarked image, the quality of the content recovery in tampered areas, and the tolerable tampering rate (TTR). -Since the birth of digital data hiding, image authentication has been one of its most widespread applications.
