A Computer-Directed System for Measuring Distance between Edges in Optical Images

reportActive / Technical Report | Accession Number: AD0771740 | Open PDF

Abstract:

An automatic measuring system for time-varying optical images is described. After the operator specifies the location of the segment to be measured on an outline image produced by the system, the equipment periodically prints the current length on a teletype. A detailed study of optical edge detection by two different transformations is given. Finally tests of the system as a means of measuring and recording dynamic blood vessel diameters in the rat mesentery are explained.
