Bag of Tricks for Long-Tail Visual Recognition of Animal Species in Camera-Trap Images. (arXiv:2206.12458v2 [cs.CV] UPDATED)

Camera traps are a strategy for monitoring wildlife and they collect a large
number of pictures. The number of images collected of each species usually
follows a long-tail distribution, i.e., a few classes have a large number of
instances, while a lot of species have just a small percentage. Although in
most cases these rare species are the ones of interest to ecologists, they are
often neglected when using deep-learning models because these models require a
large number of images …
