The microstructure analysis is a process to be carried out on ready castings. This paper is to present image processing methodology for microstructure analysis of Spheroidal Graphite Iron (SGI) castings to determine the quality assessment parameters of SGI casting such as nodularity, nodule count, nodule size and percent of ferrite-pearlite. The strength and hardness of the SGI castings is dependent on these quality parameters. Sample images of SGI casting obtained from inverted microscope were subjected to segmentation and boundary detection algorithm to find the nodules present.
