Example hole-center detection on a difficult image. On this low-contrast image, lattice fitting extends to missed holes while removing erroneous detections. (a) Input image. (b) U-Net output. (c) Centroids from high-probability regions in U-Net output (red). Many locations outside holes are detected incorrectly, and one hole (orange) is missed. (d) Running the optimal-lattice-finding algorithm results in finding lattice anchor points (cyan). (e) The lattice generated by these anchor points (cyan) results in coverage of all holes and cleans the incorrect detections.
