Image restoration in radioisotopic imaging systems
Physics in Medicine & Biology, 1967In radioisotope image visualization, the final image must be interpreted by the human visual system. However, an inherent blurring of the image limits the amount of useful information which can be extracted from it. Attempts have been made to restore the image by compensating for the degradation.

Imaging the neurovisual system
Ophthalmology Clinics of North America, 2004This article reviews the neuroimaging modalities commonly used in neuro-ophthalmology. These modalities are illustrated with several cases in an atlas format to highlight the differences between each technique. The focus is a review of MRI, MR angiography, CT,CT angiography, and digital subtraction angiography.

Memory Systems for Image Processing
IEEE Transactions on Computers, 1978An image can be represented by a two-dimensional array of "image points," which are sets of integers that each describe the color and intensity of a portion of the image. Image-processing operations require that an image or partial image be stored in a memory system that permits access to sequences of image points along any row or column of this image ...

Microwave System for Head Imaging
IEEE Transactions on Instrumentation and Measurement, 2014A wideband microwave system for head imaging is presented. The system includes an array of 16 corrugated tapered slot antennas that are installed on an adjustable platform. A switching device is used to enable the antennas to sequentially send a wideband 1-4 GHz microwave signal and capture the backscattered signals.

Proceedings of the IEEE, 1985
Recent advances in hardware technology have made feasible the design of sophisticated image information systems. There is need for image information systems in many application areas. A survey of commercial systems that are currently available indicates the diversity of product orientations, nonuniformity, and lack of integration in their capabilities.

A System for Automatic Image Categorization
2009 IEEE International Conference on Semantic Computing, 2009Traditional multimedia classification techniques are based on the analysis of either low-level features or annotated textual information. Instead, the semantic gap between rough data and its content is still a challenging task. In this paper, we describe a novel solution which automatically associates the image analysis and processing algorithms to ...

We are developing tangible imaging systems 1-4 that enable natural interaction with virtual objects. Tangible imaging systems are based on consumer mobile devices that incorporate electronic displays, graphics hardware, accelerometers, gyroscopes, and digital cameras, in laptop or tablet-shaped form-factors. Custom software allows the orientation of a

Image compression for medical imaging systems
Journal of Medical Systems, 1987The physical size of typical digital images, in terms of the number of bytes of data one image contains, is large; e.g., a 1024 X 1024 image with 8 bits of data per pixel contains a megabyte of data. To transmit many such images over a network, sometimes over low-capacity phone lines to remote sites, or to store large numbers of images over a long ...

An Interactive Image Processing System
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1981A multiuser multiprocessing image processing system has been developed. It is an interactive picture manipulation and enhancement facility which is capable of executing a variety of image processing operations while simultaneously controlling real-time input and output of pictures.
