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

Figure 6

Confusion matrices for cordon class detections for model 6 (as described in Table 2). (a) Images for the unseen test set were collected from vineyards where other images from those vineyards were used in training. (b) Images for the unseen vines comprised of vines from Block 4 which had not been used for any model training or validation the yellow off-diagonal terms have been highlighted as a ± 10 threshold has been applied in the evaluation of results in this paper. The general diagonal form of the results is evident, with some outliers (discussed below).
