Abstract

Pattern recognition techniques have some attraction for the automatic identification of seeds as they are fast, non-destructive and easily applied. In this paper, the performance of quadratic discriminant functions and one form of artificial neural network are compared for the task of identifying Australian wheat varieties. This is a complex problem as the kernels are very similar in appearance, and factors other than variety significantly influence shape. It is shown both approaches have some similarity in performance, but discriminant functions provide a superior result and are more easily applied. There is, though, some opportunity for further refinement of the artificial neural network.
