Evaluation Of 3D Voxel Rendering Algorithms For Real-Time Interaction On An SIMD Graphics Processor

Don Schreiter, John B. Zimmerman, Roger H. Schneider, Samuel J. Dwyer III
1988 Medical Imaging II  
The quality of the images produced was not high, but allowed the determination of an image orientation which could then be used by a later high-quality rendering technique.  ...  Real-time interactions, such as image rotation, utilize the motion processing capabilities of the human visual system, allowing a better understanding of the structures being imaged.  ...  Second, the correct algorithm to use for fast rendering of volume data is highly dependent upon the architecture of the display processor, and in particular upon the ability of the processor to randomly  ...

A Distributed Frame Buffer within a Window-Oriented High Performance Graphics System [chapter]

Thomas Haaker, Harald Selzer, Hans Joseph
1991 Advances in Computer Graphics Hardware IV  
Several functions of a window management system like clipping at arbitrarily shaped window boundaries, fast copying of windows and performing Bit-Block-Transfer operations (BitBIT) are performed by hardware  ...  This paper presents the architecture of a graphics engine designed to meet the above requirements. Utilizing a distributed frame buffer pixel access with a high bandwidth is achieved.  ...  A system architecture is needed where many processors perform all these tasks in order to achieve fast image generation and manipulation.  ...

A Fast, Real-Time Processor for Speckle Interferometry

T. W. Cole
1980 Publications Astronomical Society of Australia  
A second exposure 10 or so milliseconds later will show a different pattern of structure because the atmospheric irregularities will have changed.  ...  When a short exposure is taken of an image, the seeing disc (typically several seconds of arc across) is seen to contain structure (speckles) down to the resolution limit of the telescope (0″.03 arc for  ...  It will act as a display for the full 64 x 64 point processor and will be able to handle over 50 images per second -more than adequate to achieve a unique form of real-time speckle interferometry processor  ...

Orientation-Selective VLSI Retina

Tim Allen, Carver Mead, Federico Faggin, Glenn Gribble, T. Russell Hsing
1988 Visual Communications and Image Processing '88: Third in a Series  
We have constructed a silicon VLSI device containing an array of photoreceptors with additional hardware for computing center -surround (edge-enhanced) response as well as edge orientation at every point  ...  Because computing the edge orientations in the array local to each photoreceptor would have made each pixel-computation unit too large (thereby reducing the resolution of the device), we devised a novel  ...  As long as the sample-and-hold chains and the orientation processors are able to operate as fast as does the scanner, the loss of parallelism will not matter.  ...
