Abstract—We present a framework for the execution and dissemination of customizable content-based file comparison methods. Given digital objects such as files, database entries, or in-memory data structures, we are interested in establishing their

Objective Evaluation of Imager Performance

December 1, 2011
Author(s)
Francine K. Amon, Dennis D. Leber, Nicholas Paulter
We describe a method by which the evaluation and characterization of the performance of an imager can be done objectively and scientifically, that is, without routine operator interpretation. Although this method is demonstrated herein for passive long
