In Situ Active Contour-Based Segmentation and Dimensional Analysis of Part Features in Additive Manufacturing by Tushar Saini, Panos S. Shiakolas

“…This research presents a novel in situ vision-based framework for AM to identify in real-time in-layer features and estimate their shape and printed dimensions and then compare them with the as-processed layer features to evaluate geometrical differences. The framework employs a composite approach to segment features by combining simple thresholding for external features with the Chan–Vese (C–V) active contour model to identify low-contrast internal features. …”
