Camera trapping is increasingly used to monitor wildlife, but this technology
typically requires extensive data annotation. Recently, deep learning has
significantly advanced automatic wildlife recognition. However, current methods
are hampered by a dependence on large static data sets when wildlife data is
intrinsically dynamic and involves long-tailed distributions. These two
drawbacks can be overcome through a hybrid combination of machine learning and
humans in the loop. Our proposed iterative human and automated identification
approach is capable of learning from wildlife imagery data with a long-tailed
distribution. Additionally, it includes self-updating learning that facilitates
capturing the community dynamics of rapidly changing natural systems. Extensive
experiments show that our approach can achieve a ~90% accuracy employing only
~20% of the human annotations of existing approaches. Our synergistic
collaboration of humans and machines transforms deep learning from a relatively
inefficient post-annotation tool to a collaborative on-going annotation tool
that vastly relieves the burden of human annotation and enables efficient and
constant model updates.

Iterative Human and Automated Identification of Wildlife Images

Non intrusive monitoring of animals in the wild is possible using camera
trapping framework, which uses cameras triggered by sensors to take a burst of
images of animals in their habitat. However camera trapping framework produces
a high volume of data (in the order on thousands or millions of images), which
must be analyzed by a human expert. In this work, a method for animal species
identification in the wild using very deep convolutional neural networks is
presented. Multiple versions of the Snapshot Serengeti dataset were used in
order to probe the ability of the method to cope with different challenges that
camera-trap images demand. The method reached 88.9% of accuracy in Top-1 and
98.1% in Top-5 in the evaluation set using a residual network topology. Also,
the results show that the proposed method outperforms previous approximations
and proves that recognition in camera-trap images can be automated.
