The challenge will explore the use of CV techniques for endangered wildlife conservation, specifically focusing on the Amur tiger, also known as Siberian tiger or the Northeast-China tiger. The Amur tiger population is concentrated in the Far East, particularly the Russian Far East and Northeast China. The remaining wild population is estimated to be 600 individuals, so conservation is of crucial importance.
Dataset: With the help of WWF, a third-party company (MakerCollider) collected more than 8,000 Amur tiger video clips of 92 individuals from ~10 zoos in China. This raw dataset is donated to us for academic usage. We organize efforts to make bounding-box, keypoint-based pose, and identity annotations for sampled video frames and formuate the ATRW (Amur Tiger Re-identification in the Wild) dataset. Figure 1 illustrates some example bounding box and pose keypoint annotations in our ATRW dataset. Our dataset is the largest wildlife re-ID dataset to date, Table 1 lists a comparison of current wildlife re-ID datasets. The dataset will be divided into training, validation, and testing subsets. The training/validation subsets along with annotations will be released to public, with the annotations for the test subset withheld by the organizers.
|#Images or #Clips||8,076*||278||2,109||5,078||2,078||924|
|#BBoxes with ID||3,649||278||2,109||5,078||2,078||924|
Requirement: We require that participants agree to open-source their solution to support wildlife conservation. All participating teams are required to use only our dataset for training, and submit their challenge results as well as full source-code packages for evaluation.
Tiger Detection: From images/videos captured by cameras, this task aims to place tight bounding boxes around tigers. As the detection may run on the edge (smart cameras), both the detection accuracy (in terms of AP) and the runtime cost are used to measure the quality of the detector.
Tiger Pose Detection: From images/videos with detected tiger bounding boxes, this task aims to estimate tiger pose (i.e., keypoint landmarks) for tiger image alignment/normalization, so that pose variations are removed or alleviated in the tiger re-identification step. We will use mean average precision (mAP) and object keypoint similarity (OKS) to evaluate submissions.
Tiger Re-ID with Human Alignment (Plain Re-ID): We define a set of queries and a target database of Amur tigers. Both queries and targets in the database are already annotated with bounding boxes and pose information. Tiger re-identification aims to find all the database images containing the same tiger as the query. Both mAP and rank-1 accuracy will be used to evaluate accuracy.
Tiger Re-ID in the Wild: This track will evaluate the accuracy of tiger re-identification in wild with a fully automated pipeline. To simulate the real use case, no annotations are provided. Submissions should automatically detect and identify tigers in all images in the test set. Both mAP and rank-1 accuracy will be used to evaluate the accuracy of different models.
