- Abstract: Wildlife camera traps and crowd-sourced image material provide novel
possibilities to monitor endangered animal species. However, massive image
volumes that these methods produce are overwhelming for researchers to go
through manually which calls for automatic systems to perform the analysis. The
analysis task that has gained the most attention is the re-identification of
individuals, as it allows, for example, to study animal migration or to
estimate the population size. The Saimaa ringed seal (Pusa hispida saimensis)
is an endangered subspecies only found in the Lake Saimaa, Finland, and is one
of the few existing freshwater seal species. Ringed seals have permanent pelage
patterns that are unique to each individual which can be used for the
identification of individuals. Large variation in poses further exacerbated by
the deformable nature of seals together with varying appearance and low
contrast between the ring pattern and the rest of the pelage makes the Saimaa
ringed seal re-identification task very challenging, providing a good benchmark
to evaluate state-of-the-art re-identification methods. Therefore, we make our
Saimaa ringed seal image (SealID) dataset (N=57) publicly available for
research purposes. In this paper, the dataset is described, the evaluation
protocol for re-identification methods is proposed, and the results for two
baseline methods HotSpotter and NORPPA are provided. The SealID dataset has
been made publicly available.

We conduct a study by revisiting several state-of-the-art person re-identification methods, including BoT, AGW, SBS, and MGN.
We evaluate their effectiveness on animal re-identification benchmarks such as HyenaID, LeopardID, SeaTurtleID, and WhaleSharkID.
Our findings reveal that while some techniques well, many do not generalize, underscoring the significant differences between the two tasks.

Seafloor imagery collected by Autonomous Underwater Vehicles (AUVs) can be used to identify individuals within their broader habitat context.
Machine learning models can be used to identify the presence of a particular species in images using a trained object detector.
In this paper, inspired by recent work in few-shot learning, images and annotations of common marine species are exploited to enhance the ability of the detector to identify rare and cryptic species.

Animal Re-ID is crucial for wildlife conservation, yet it faces unique challenges compared to person Re-ID.
This study addresses background biases by proposing a method to systematically remove backgrounds in both training and evaluation phases.

Motion-activated camera traps constitute an efficient tool for tracking and monitoring wildlife populations across the globe.
Supervised learning techniques have been successfully deployed to analyze such imagery, however training such techniques requires annotations from experts.
Reducing the reliance on costly labelled data has immense potential in developing large-scale wildlife tracking solutions with markedly less human labor.

Image-based re-identification of animal individuals allows gathering of information such as migration patterns of the animals over time.
For many species, the re-identification can be done by analyzing the permanent fur, feather, or skin patterns that are unique to each individual.
In this paper, we address the re-identification by combining two types of pattern similarity metrics.

We aim to locate and provide a unique identifier for each mouse in a cluttered home-cage environment through time.
This is a very challenging problem due to (i) the lack of distinguishing visual features for each mouse, and (ii) the close confines of the scene with constant occlusion.
Our approach achieves 77% accuracy on this animal identification problem, and is able to reject spurious detections when the animals are hidden.

We show that it is possible to transfer the knowledge existing in dense pose recognition for humans, as well as in more general object detectors and segmenters, to the problem of dense pose recognition in other classes.
We do this by establishing a DensePose model for the new animal which is also geometrically aligned to humans.
We also introduce two benchmark datasets labelled in the manner of DensePose for the class chimpanzee and use them to evaluate our approach.
