A Comparative Study of Fruit Detection and Counting Methods for Yield Mapping in Apple Orchards

no code implementations22 Oct 2018 Nicolai Häni, Pravakar Roy, Volkan Isler

We present new methods for apple detection and counting based on recent deep learning approaches and compare them with state-of-the-art results based on classical methods.
