Computerized pattern recognition used for grain counting in high resolution autoradiographs with low grain densities.
Using a video-image system coupled to a minicomputer with commercial image handling software, autoradiographic grains displayed in dark-field are counted with a fast (ca. 3.5 min for 120,000 microns 2) and reliable (false scores less than 5%) grain-recognizing FORTRAN program executed in the users memory. The grain counts are printed in a raster of adjustable size overlying a bright-field image, so that the counts can be related directly to the underlying histological structures.
