Scanning, optimisation and AI in the sawmill

Digital tools · Advanced

How log and board scanners, cutting optimisation and machine-vision models are evaluated in the open literature: what is measured, what the gains are (mostly simulated), how to read precision, recall and mAP, and how a small mill can start.
