Using a Camera System for the In-Situ Assessment of Cordon Dieback due to Grapevine Trunk Diseases

Figure 3

(a) The distribution of vine cordon GTD labels for imagery collected in the 2022 vintage. (b) The more balanced distribution of vine cordon GTD labels used for training the models, using data collected from both 2021 and 2022 vintages. Zero indicates no GTD symptoms observed, and 50 indicates complete dieback for that cordon. The total number of cordons is approximately twice the number of vines as indicated by the number of trunks identified.
