Images are often produced from data obtained with nondestructive evaluation (NDE) techniques to take advantage of the human ability to visually detect patterns and changes in acquired data. An ultrasonic imaging technique was applied to detect flaws and predict failure locations in ceramic modulus-of-rupture (MOR) bars. After fracture and subsequent fractographic analysis, the ultrasonic NDE data were correlated with digitized optical images of the MOR bars to determine if the location of the failure-initiating flaw had been detected by the ultrasonic technique. This paper describes the microcomputer-based digital image processing method used to correlate the fractographic analysis with NDE data. An algorithm which can be used to implement the technique on most imaging workstations will be presented, along with results obtained with an IBM-PC. 4 refs., 6 figs.
