Fig. 6 present the set of all n=162 kernels Ti used to localize the beans. We used elliptical
kernels with three eccentricities, three scales, rotated in 18 angles. This set of kernels
contains all possible shapes of the beans. If you want (for example) find smaller
grains, smaller kernels should be included in the set. If you want to find (for example)
more elongated grains, kernels with higher eccentricity should be included in the set.
