Table 3 Distribution of \(D_{\text {mean}R}^{i}\) and \(D_{\text {max}R}^{i}\) computed assuming \(\text {Ell}_{f4}^{i}\) or \(\text {Ell}_{\text {opt}}^{i}\) as the final segmentation for the images of category 1. Also shown are the total number of images (N ₁) of category 1 for each sequence and the number of images N _c where the position of the tomato is correctly estimated \(\left (D_{\text {desc}}^{i}<\frac {{r_{s}^{i}}}{2}\right)\). Only four images were discarded using this criterion
