Scientific American, 2008
The article discusses the field of digital image forensics, which involves the detection of photographic fraud, which has become increasingly problematic given the widespread availability of digital image manipulation software. Simple tests such as looking for incompatible shadows are discussed, as are more advanced mathematical methods involving the ...

3D Imaging in Forensic Odontology
Journal of Visual Communication in Medicine, 2010This paper describes the investigation of a new 3D capture method for acquiring and subsequent forensic analysis of bite mark injuries on human skin. When documenting bite marks with standard 2D cameras errors in photographic technique can occur if best practice is not followed.

StegoAppDB: a Steganography Apps Forensics Image Database
IS&T International Symposium on Electronic Imaging, 2019 In this paper, we present a new reference dataset simulating digital evidence for image (photographic) steganography. Steganography detection is a digital image forensic topic that is relatively unknown in practical forensics, although stego app use in ...

Characteristics of Forensic Imaging Performance—An Analysis of Forensic Imaging Bottlenecks
Journal of Forensic Sciences, 2013AbstractDisk imaging involves copying all of the data from a source disk drive to a target. Typically, the target for the copy is another disk drive. Forensic processes developed years ago do not appear to be adequate for current storage technology. For example, with disk drive capacities now exceeding 1 Terabyte, a typical disk imaging can take over 8

Image forensics and anti-forensics for generative AI
2023Recent advancements in deep learning have paved the way for a new category of image forensics algorithms that utilize contrastive machine learning. These algorithms are designed to capture general forensic characteristics from digital images that have undergone various image processing and post-processing histories.

Image processing of forensic documents
Proceedings of 3rd International Conference on Document Analysis and Recognition, 2002Since the middle of the seventies, a number of research projects have been developing computer assisted methods for work in forensic document examination. Special programs have been developed and commercial software has been adapted to the practical requirements of this work as well. The paper discusses a number of European image processing systems and

Image Processing in Forensic Pathology
Clinics in Laboratory Medicine, 1998Image processing applications in forensic pathology are becoming increasingly important. This article introduces basic concepts in image processing as applied to problems in forensic pathology in a non-mathematical context. Discussions of contrast enhancement, digital encoding, compression, deblurring, and other topics are presented.

Revue medicale suisse, 2008
In recent years, modern techniques of medical imaging such as MDCT (multidetector-computed tomography) and MRI (magnetic resonance imaging) have pioneered post mortem (pm) investigations, especially in forensic medicine. Particularly pm angiography permits investigating the vascular system in a way which is not possible by performing only conventional ...

Journal of Forensic Radiology and Imaging, 2013
Our radiology department started in 2006 with advanced forensic imaging (virtual autopsies). Soon, after we build up some experience in scanning bodies, we realized that forensic evidence was not the only information a corps could reveal. For instance, a lot of data generated by a CT scan can be used for dosimetric purposes. As presented at the RSNA in
