Next: Search Algorithms Up: Computational Methods Previous: Image Restoration . The previous sections have described the most frequently used computational techniques for image handling in optical astronomy. After the images have been calibrated and manipulated to give the best representation of the data the astronomical information has to be extracted. For frames which contain a large number of objects automatic methods are required to locate them. ... Search Algorithms . ...

... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...
