description: Saimaa and Ladoga ringed seals are on the verge of extinction. Presently a large number of images collected by camera traps installed on the lakes allows animal reidentification and presents new opportunities for biologists in their efforts of ringed seals conservation. This study aims to determine novel approaches for the reidentification of Saimaa ringed seals while taking into account high animal pose variation. In particular, it is explored how global pooling methods can be improved and applied to our task. In addition, a novel layer for global pooling - EDEN is introduced. It is capable of collecting information about the distribution of features in activation maps. This is done by finding an eigen decomposition of the covariance matrix for the probability mass function representing the spatial distribution of features in the feature map. Experiments show that EDEN outperforms existing pooling methods on a challenging dataset of Saimaa ringed seals images.
