Exposing digital forgeries by detecting traces of resampling
The unique stature of photographs as a definitive recording of events is being diminished due, in part, to the ease with which digital images can be manipulated and altered. Expand

A Survey of Image Forgery Detection
We are undoubtedly living in an age where we are exposed to a remarkable array of visual imagery. While we may have historically had confidence in the integrity of this imagery, today’s digitalExpand

The image of an object can vary dramatically, depending on lighting, specularities, reflections, and shadows. It is often advantageous to separate these incidental variations from the intrinsicExpand

Differentiation of Discrete Multi-Dimensional Signals
We describe the design of finite-size linear-phase separable kernels for differentiation of discrete multi-dimensional signals. The problem is formulated as an optimization of the rotation-invarianceExpand

Range estimation by optical differentiation.
We describe a novel formulation of the range recovery problem based on computation of the differential variation in image intensities with respect to changes in camera position. This method uses aExpand

Digital Image Ballistics from JPEG Quantization
A comparison of an image's quantization scheme to a database of known cameras affords a simple technique for confirming or denying an image’s source. Expand

Separating Reflections from Images Using Independent Components Analysis
The image of an object can vary dramatically depending on lighting, specularities/reflections and shadows. It is often advantageous to separate these incidental variations from the intrinsic aspectsExpand
