Techniques for rapid searches of photographic plates

Edwin L. Turner

Research output: Contribution to journalArticlepeer-review


A set of schemes for locating objects of interest (color, variability, morphological form, etc.) by automated search of photographic plates is described. These techniques are designed to allow rapid and efficient processing of large areas of plate and to make minimal demands on the homogeneity and calibration of the plate material. They are based in part on the techniques of nonparametric statistics. Projects using these methods which are currently being carried out with the Princeton PDS microdensitometer and image processing system are also briefly described.
