Measuring out these image parameters yields PSF, that itself more approaches to original. At factual conditions the light emitting point appears as a circular aggregation of light spots, with fading intensity depending on the radius. Circular aggregation increases in radius with clearance of in-focus plains. Empirical PSF 4. Future work Work presented in this paper provides compact tool for processing of image obtained via CCD camera connected to optical devices.
Algorithms use either theoretical or empirically measured approximation of point spread function.
Merely small number of physical parameters is considered in existing models of point spread function. Considering more parameters there appears the possibility of more accurate modeling of point spread function for individual optical systems. This seems to be vast and very rich field, which offers amount of opportunities for research. The aim of this work was to collect various methods of image preprocessing, their improving and implementation. These techniques try to give human instruments for better understanding, storage and further processing of acquired images.
