Curculionidae-alpha

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
