Abstract

Surface texture comprises of many features of interest, which may or may not be essential for surface functional requirements. Features on the surface topography data refers to the peak, pit and the relationship between them; instead of the point on the valleys only. Hence, the objective of this paper is to demonstrate the watershed segmentation on the simulated surface topography data. Watershed segmentation is applied on the selected areal surface texture to determine the regions of the features of the hill and dales. The segmentation of the features is developed by using MATLAB. The developed application is then validated with the simulated topography data. The application’s result on the simulated data shows that, the watershed segmentation method works as intended.
