SIMPLIcity: Semantics-Sensitive Integrated Matching for Picture LIbraries

by James Z. Wang, Jia Li, Gio Wiederhold - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2001
"... The need for efficient content-based image retrieval has increased tremendously in many application areas such as biomedicine, military, commerce, education, and Web image classification and searching. We present here SIMPLIcity (Semanticssensitive Integrated Matching for Picture LIbraries), an imag ..."

system performs significantly better and faster than existing ones. The system is fairly robust to image alterations.

Brain magnetic resonance imaging with contrast dependent on blood oxygenation.

by S Ogawa , T M Lee , A R Kay , D W Tank - Proc. Natl. Acad. Sci. USA , 1990
"... ABSTRACT Paramagnetic deoxyhemoglobin in venous blood is a naturally occurring contrast agent for magnetic resonance imaging (MRI). By accentuating the effects of this agent through the use of gradient-echo techniques in high fields, we demonstrate in vivo images of brain microvasculature with imag ..."

with image contrast reflecting the blood oxygen level. This blood oxygenation level-dependent (BOLD) contrast follows blood oxygen changes induced by anesthetics, by insulininduced hypoglycemia, and by inhaled gas mixtures that alter metabolic demand or blood flow. The results suggest that BOLD contrast can

Detection of Image Alterations Using Semi-Fragile Watermarks

by Eugene T. Lin , Christine I. Podilchuk , Edward J. Delp , 2001
"... Digital watermarking research has generally focused upon two classes of watermarks, fragile and robust. Robust watermarks are designed to be detected even after attempts are made to remove them. Fragile watermarks are used for authentication purposes and are capable of detecting even minute changes ..."

change the expression of the content. In this paper we describe a semi-fragile watermark for still images that can detect information altering transformations even after the watermarked content is subjected to information preserving alterations.

Digital Image Alteration Detection using Advance Processing

by Mahesh Mahipati Patil, Savitribai Phule Pune, S. P. Rangdale, Savitribai Phule Pune, S. A. Nalawade, Savitribai Phule Pune
"... Digital images became the part of many applications. But digital images have the problem of image retouch up techniques. Because of this retouch up techniques there is serious problem of securing digital images.To touch upon this downside, the sphere of digital forensics and investigation has emerge ..."

Collusion-Secure Fingerprinting for Digital Data

by Dan Boneh, James Shaw - IEEE Transactions on Information Theory , 1996
"... This paper discusses methods for assigning codewords for the purpose of fingerprinting digital data (e.g., software, documents, and images). Fingerprinting consists of uniquely marking and registering each copy of the data. This marking allows a distributor to detect any unauthorized copy and trac ..."

Functional Brain Imaging Alterations in Acne Patients Treated With Isotretinoin

by J. Douglas Bremner, Negar Fani M. S, Ali Ashraf M. D, John R. Votaw, Ph. D, Marijn E. Brummer, Thomas Cummins M. D, Mark M. Goodman, Ph. D, Lai Reed M. B. A, Sajid Siddiq M. D, Charles B. Nemeroff, Ph. D
"... Objective: Although there have been case reports suggesting a relationship be-tween treatment with the acne medica-tion isotretinoin and the development of depression and suicide, this topic remains controversial. In order for isotretinoin to cause depression, it must have an effect on the brain; ho ..."

Objective: Although there have been case reports suggesting a relationship be-tween treatment with the acne medica-tion isotretinoin and the development of depression and suicide, this topic remains controversial. In order for isotretinoin to cause depression, it must have an effect on the brain; however, the effects of isotretinoin on brain functioning in acne patients have not been established. The purpose of this study was to assess the ef-fects of isotretinoin on brain functioning in acne patients. Method: Brain functioning in adults was measured with [18F]fluorodeoxyglucose

Exposing Digital Forgeries by Detecting Traces of Re-sampling

by Alin C. Popescu, Hany Farid - IEEE Transactions on Signal Processing , 2004
"... 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. Although good forgeries may leave no visual clues of having been tampered with, they may, nevertheless, alter the underlying s ..."
