Abstract

The size distribution of somatotroph secretory granules on electronmicrographes of rat adenohypophysis is automatically detected by two methods; 1) "erosion-chord method" and 2) "distance-maximum method". In the later method, the diameter of each disc of the granules is automatically detected in a way which depends upon Rosenfeld's distance function. In the former method, the Serra's erosion is employed prior to the detection of the chord length to separate the profile of the granules on the electron micrographs. The two results are compared with the results using the manual methods. In these analyses, the thickness of the section is stereologically introduced.
