The concept of simulating chosen information channels of a linear incoherent imaging system by projecting reference signals is proposed and the system's ability to restore severely distorted but stationary images is experimentally demonstrated. A particular instrument's object field is divided into N discrete 'points' whose individual simulated outputs is measured at N particular sampling point...

Rapid advances are occurring in the field of cytopathology, particularly in the field of digital imaging. Today, digital images are used in a variety of settings including education (E-education), as a substitute to multiheaded sessions, multisite conferences, publications, cytopathology web pages, cytology proficiency testing, telecytology, consultation through telecytology, and automated scre...

In this paper we will describe the design, construction and application of a wearable digital imaging project based on the PC/104 embedded PC board [1]. The systems for image capture, manipulation and communication will be presented and power-consumption, heat dissipation and user-interface design will be considered. The paper will also discuss the results of an archaeological field trial and d...

The convergence of inexpensive digital cameras and cheap hardware for displaying stereoscopic images has created the right conditions for the proliferation of stereoscopic imaging applications. One application, which is of growing importance to museums and cultural institutions, consists of capturing and displaying 3D images of objects at multiple orientations. In this paper, we present our ste...

This review of digital imaging and the technical aspects of radiographic equipment manufactured for dentists is designed to provide practical information to assist in the decision making process and purchase of radiographic digital imaging for clinical use.

This unit presents an overview of digital imaging hardware used in light microscopy. CMOS, CCD, and EMCCDs are the primary sensors used. The strengths and weaknesses of each define the primary applications for these sensors. Sensor architecture and formats are also reviewed. Color camera design strategies and sensor window cleaning are also described in the unit.

For more than a century, now radiographs have been taken using radiographic film. Digital imaging has been replacing traditional films in private practice, academic institutions in the last two decades. As use of digital radiography has become more common in the last decade with rapidly evolving changes in the way healthcare is administered, coupled with the amazing recent advances in imaging, ...

background and aims. digital imaging continues to gain acceptance in dentistry and video display used for this becomes important. the aim of this study was to assess the influence of the display monitor on observer performance on caries detection. materials and methods. artificial enamel lesions were created in 40 extracted teeth at random using 1/4 and 1/2 round burs. teeth were mounted in den...
