Abstract

An image processing system has been developed around an APOLLO workstation, tailored to the needs of processing images of photoelastic models. Using this system, the authors have made a comparative study of some image processing algorithms in the analysis of a disc of araldite resin loaded in diametral compression. A differential zero crossing algorithm has been developed and the results obtained compared with those from the other algorithms. The algorithms used are described, and an analysis of their effectiveness in this problem presented, with the aid of a fringe analysis system developed to analyse output from the image processing system. The results are compared with results from finite element analysis and mathematical modelling.
