Image magnification is a common problem in imaging applications, requiring interpolation to " read between the pixels ". Although many magnification/interpolation algorithms have been proposed in the literature, all methods must suffer to some degree the effects of imperfect reconstruction—false high-frequency content introduced by the underlying original… (More)
Standard methods for image interpolation are based on smoothly fitting the image intensity surface. Recent edge-directed interpolation methods add limited geometric information (edge maps) to build more accurate and visually appealing interpolations at key contours in the image. This paper presents a method for geometry-based interpolation that smoothly… (More)
We report a case of a vesicouterine fistula with menouria (vesical menstruation) secondary to an intrauterine contraceptive device. Of the 23 cases of menouria reported previously 21 occurred after cesarean section, 1 was secondary to a traumatic forceps delivery and 1 was owing to infection. In our case the fistula did not close after removal of the… (More)
Vesical endometriosis is the abnormal growth of endometrial tissue in the bladder. Usually small lesions occur. Three cases of endometriosis of the bladder are presented. Each case demonstrates a large intravesical lesion with striking radiographic findings that are indistinguishable from an intravesical neoplasm.
Proteomics is a rapidly emerging field of research that will help identify and characterize the complex proteins that are responsible for the function of complex biological systems. For detection and identification of separated components, mass spectrometry is evolving to be the method-of-choice because of its high sensitivity and its ability to… (More)
FOREWORD The research described in this report was performed at the Naval Air Warfare Center Weapons Division during fiscal year 2006 as an attempt to apply swarm-based algorithms that were previously tested in simulation to hardware. Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time… (More)
