A vision system for measuring the area of an arbitrarily shaped object is described. The algorithm consists of a gray-level thresholding technique combined with a region correction procedure based on mathematical morphology. All processing steps are carried out on a microcomputer system equipped with a video digitizer. The algorithm has been successfully applied to a number of images of medical interest including skin wounds and various microscopic-scale objects such as cell cross-sections and multicellular tissues. Excellent agreement between results obtained by the automatic method and by using standard mechanical means has been established experimentally. The approach is demonstrated by a number of experimental examples.

D007515	Islets of Langerhans	Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.
