Image Processing in Radio Astronomy
Integrated Computational Imaging Systems, 2001Image Processing has enabled large improvements in the performance of radio telescopes. Non-linear deconvolution and adaptive (self-) calibration techniques were developed in radio astronomy in the seventies and eighties. These processing techniques are now part of the standard tool kit used by any radio astronomer.

Aesthetics and Digital Image Processing: Representational Craft in Contemporary Astronomy
The Sociological Review, 1987This paper examines whether ‘aesthetic’ considerations play a part in contemporary scientific work, and focuses on a scientific field undergoing rapid transformation through the introduction of digital imaging and image processing technologies. Interviews with astronomers at two image processing laboratories indicate that they orient explicitly to the

Machine learning and image processing in astronomy with sparse data sets
2014 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2014Automated classification systems have allowed for t he rapid development of digital large sky surveys. Such systems increase the independence of human intervention in the analysis stage of star and galaxy classification. Artificial neural networks, hierarchicalclassifiersand ensemblesof classifiershavebeen used as the methods of classification in these

Data Compression Techniques in Image Processing for Astronomy
1985The classical way to digitally encode an image consists in sampling it on the nodes of a two dimensional grid and assigning to each pixel (picture element) a numerical value which expresses, to a desired accuracy, the luminance value on that node. A digital image can, therefore, be thought of as a matrix. Fig.

A Real-Time Parallel-Processing Imaging System for Radio Astronomy
2003ACSIS (Auto Correlation Spectrometer Imaging System) is a real- time data collection and reduction system intended for use with a 16 pixel receiver at the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. At peak operating speed, the correlator connected to each receiver will generate an autocorrelation lag array of 8192 numbers every 50 ms, or 10.5 ...

SPIE Proceedings, 2014
Image processing techniques can be used to improve the cost-effectiveness of future interferometric Passive MilliMetre Wave (PMMW) imagers. The implementation of such techniques will allow for a reduction in the number of collecting elements whilst ensuring adequate image fidelity is maintained.

Data Structures and Languages in Support of Parallel Image Processing for Astronomy
1985Data structures, and aspects of programming languages and programming systems that are relevant to image processing of astronomy data are discussed. Since parallel processing promises to greatly increase the speed with which images can be analyzed, techniques that will help achieve this speed and new methods that may become possible because of it are ...

SPIE Proceedings, 1984
This paper describes a family of image management systems which require massive archival capabilities. The Multimodal Acquisition, Archive and Review System needs a storage media which can be preserved for legislated time periods of five to ten years, with storage for childrens cases up to 21 years.

An Overview of the Digitized Astronomy Supernovae Search Control and Image Processing Software
1988A 75-cm telescope has been automated with a Prime 300 minicomputer to search approximately 250 galaxies per hour for premaxima supernovae. The telescope operates completely automatically and without a human operator. The computer handles all aspects of the search including startup and shutdown, weather monitoring, object scheduling, and the generation ...
