A simple retinanet_R_101_FPN model to detect (bounding box) and classify insects between these four species:
- Animalia Arthropoda Insecta Coleoptera Curculionidae Cactophagus spinolae
- Animalia Arthropoda Insecta Coleoptera Curculionidae Cyrtepistomus castaneus
- Animalia Arthropoda Insecta Coleoptera Curculionidae Diaprepes abbreviatus
- Animalia Arthropoda Insecta Coleoptera Curculionidae Larinus carlinae
