- Abstract: Vision-based pattern identification (such as face, fingerprint, iris etc.)
has been successfully applied in human biometrics for a long history. However,
dog nose-print authentication is a challenging problem since the lack of a
large amount of labeled data. For that, this paper presents our proposed
methods for dog nose-print authentication (Re-ID) task in CVPR 2022 pet
biometric challenge. First, considering the problem that each class only with
few samples in the training set, we propose an automatic offline data
augmentation strategy. Then, for the difference in sample styles between the
training and test datasets, we employ joint cross-entropy, triplet and
pair-wise circle losses function for network optimization. Finally, with
multiple models ensembled adopted, our methods achieve 86.67\% AUC on the test
set. Codes are available at https://github.com/muzishen/Pet-ReID-IMAG.

Occluded Person Re-Identification (ReID) is a metric learning task that involves matching occluded individuals based on their appearance.
We introduce Keypoint Promptable ReID (KPR), a novel formulation of the ReID problem that explicitly complements the input bounding box with a set of semantic keypoints.
We release custom keypoint labels for four popular ReID benchmarks. Experiments on person retrieval, but also on pose tracking, demonstrate that our method systematically surpasses previous state-of-the-art approaches.

We explore the possibility of using different types of "soft" biometrics, such as breed, height, or gender, in fusion with "hard" biometrics such as photographs of the pet's face.
The proposed network is able to achieve an accuracy of 90.80% and 91.29% when differentiating between the two dog breeds.
