Polyphyletic Loss: Litchi Flower Detection with Occlusion

Abstract Controlling shoot and promoting flower of litchi is one the key technologies for high yield fruit trees, but occlusion caused by dense growth has a great impact on detection flowers. To solve problem, this paper designs polyphyletic loss function to detect occlusive A new aggregation term proposed in force proposal box approach compactly locate corresponding target. At same time, segmentation bounding specially designed crop scene added keep prediction away from surrounding objects improve robustness detecting large number We conducted experiments self-built data set multi species at time. Compared with other methods, method higher accuracy, which provides an important idea statistics scenes.
